3 New Home Assistant Integrations: Niagara AX/N4, Crestron CIP, and Daikin DBACS

Hey everyone! I’ve been working on a few open-source projects designed to bridge commercial and enterprise automation systems directly into Home Assistant.

All three integrations are currently in BETA (developed with the help of AI coding tools), and I’d love to get feedback, bug reports, or feature requests from the community.

1. Niagara to Home Assistant (Niagara--HA)

• Type: Integration (Read-Only)
• What it does: Uses OBIX to import points from Niagara Workstations directly into Home Assistant.
• Repo:github.com/rellis-erigon/Niagara--HA

2. Crestron Touch Panel Integration (Crestron-CIP-HA)

• Type: Integration / Web View
• What it does: Allows you to load Crestron Touch Panel files (zipped files from the Display folder) and interact with the touch panel directly within Home Assistant. (Currently testing CP3 files as well).
• Repo:github.com/rellis-erigon/Crestron-CIP-HA

3. Daikin DBACS-III HVAC Control (HA-Daikin-DBACS)

• Type: Custom Component (Full Control)
• What it does: Interfaces with Daikin DBACS-III connected AC units. Pulls all available telemetry data and gives full control over connected HVAC units.
• Repo:github.com/rellis-erigon/HA-Daikin-DBACS

Feedback Requested

Since these are in Beta, I'm especially looking for feedback on:

• Installation issues or setup friction
• Point mapping accuracy across different Niagara setups
• UI/Control responsiveness on Crestron panels and DBACS units

Feel free to test them out, open issues on GitHub, or leave your thoughts below!

Is anyone else having issues with the SIMPL compiler being blocked by Windows Security?

I've seen reports of this happening with 3rd party virus checkers before, but not with Windows Security.

Is there anyone with a DM-NVX-350 setup with a transmitter and multiple receivers with multi-device USB that functions? I feel like I have to be missing something obvious here.

Video stream is fine.

Latest firmware on everything.

On the transmitter 350, USB is plugged into the PC (yes, it's the right port - type-B labeled Device).
On the receiver(s), a USB hub is plugged in with a keyboard. (I've tried many hubs and single devices at this point as well)

Multi-device is enabled on the transmitter and the receivers. (I've tried this disabled on the receivers with no change in behavior)

Remote Device ID from the transmitter is plugged into the receiver and vice-versa - they both show as paired.

Streaming routing has USB follows Video set on the receiver - Although this goes "orange" briefly and then shows as gray. Turning off USB follows Video and manually clicking the USB icon under routing seems to clear out the pairing, so I have to start over, so I'm a bit uncertain how these things interact.

The PC that is connected to the transmitter does not show a USB Hub connection...

UNTIL...

I turn off Multi-Device support on the Transmitter, the USB Hub pops up in Device Manager, and everything works (with whatever device or USB hub I have plugged the single paired receiver).

The second I turn multi-device support back on, the USB hub disappears and it ceases to work.

I've reset everything to factory defaults, reconfigured. No clue what I'm botching up. It clearly isn't a hardware issue as it works fine the second I turn of multi-device support.

Can anyone give me a tiny clue?

Just an FYI they have it.... You can set credentials and update the firmware for everything at the same time. Cannot understand why they are not telling about this software anywhere. Support agent recommended to use it.

Bei unserem GE PACSystems RX3i mit IC695CMM004 verliert ein Port wiederholt die Verbindung, obwohl die physische Verbindung intakt ist. Nach einem Reset über PAC Machine Edition funktioniert er vorübergehend wieder, bis die Port-Fault-LED an der SPS orange leuchtet und die Verbindung erneut abbricht.
Hat jemand eine Idee, woran das liegen könnte oder wie ich die Ursache diagnostizieren kann?

What is the easiest way to get access to the software? Need to upgrade and add a few Crestron thermostats to an existing system; will have to upgrade the processor as well. I only need to do the thermostats; I am already controlling the rest of the residence from Elan/Nice.

Hi there, I have an AM-3200-WF device behind the TV display, which seems to be preventing the TV display from going to sleep when no one is using the USB-C cable connected to the AM-TX3-200. I was wondering if anyone has any idea how to make the AM-3200-WF go to sleep when no one is using the USB-C cable? Or any settings that can be done on the TV display to make it go to sleep?

Custom C# program on a CP4N (SDK 2.21.274), driving the relay on a DM-RMC-4K-SCALER-C (fw 1.2911.00057). The RMC connects through a DM-MD16X16-CPU3.

I'm trying to work out what the relay does when it's closed and the control path goes away (e.g. if the DM link drops, the switcher drops, or the CP4N program or processor crashes; or more likely, some knucklehead unplugs something mid relay pulse). As far as I can tell, the relay just stays in its last state. I'd like a fail-safe that doesn't depend on the control path/processor still being alive to send OPEN.

Two questions:

1. Does the RMC have any supported way to time out or auto-release a relay locally, so it keeps working through a DM loss, a switcher loss, or a CP4N failure? Something like a pulse with a duration, a watchdog, or an "open on comm loss" setting I'm not aware of. If it exists (maybe in newer firmware?), does anyone know:

• Which API, join, or console command sets it
• The min/max duration and resolution
• What happens on power loss or reboot (does the relay come up open? does the timer persist?)
• Which firmware versions support it

2. Is there a supported way to force-send OPEN without first sending CLOSE? When the program thinks the relay is already open (e.g. testing a DM link loss mid relay pulse), calling `Open()` doesn't seem to send anything to the device - I'm guessing the framework drops it as a no-change since it thinks its already open.

(I know a forced OPEN doesn't help if the path to the RMC is down. That's why Q1 is the real question. Q2 is about making sure the state is right after the path comes back.)

If the answer is "no, use an external timer relay," that's useful too. Thanks!

Tried resetting TSW-1070 using the 11x reset button with crestron logo, now unit just keeps rebooting. Any guidance/help would be greatly appreciated

First time posting here since I'm at wit's end with my current project.

I've managed to connect the Crestron CP4 to the Cisco Codec using the "Cisco Room Devices 6.0.3 (cm)" driver on my SIMPL Windows. I can see the Volume levels changing on my SIMPL debugger when I change it on the Cisco Room Navigator. But I can't for the life of me find any resource on how/where to get the Crestron CP4 to see the Button Presses on the Cisco UI Extensions buttons. Is there a driver I'm missing? Or am I doing something wrong?

Any help is appreciated.

Hi all in Crestron construct how to GUI program Load in IPAD?

I currently have a system running on a DMPS3-4K-350-C and am wanting to add a DM-MD8x8 for additional IO. I am struggling how to program it in SIMPL.

Any help is appreciated

Hi All,

This is a workaround that I have tested with the issue where the Crestron Impress version 1.03.062.02 installs and asks for an update. It will then stop at downloading and won't progress. If you Cancel the download, and reselect it for downloading, it will proceed but will end up with an error. Here's what I do.

1) Download an older version of Impress (I used 1.01.002.00).

2) After you installed that version, trigger an update and open the path C:\ProgramData\Crestron\Impress\Data\Packages\Downloaded\PackageInstaller. Keep this explorer open.

3) Watch and when the "Data" folder appears, copy PackageInstaller.zip from that folder and paste it somewhere else.

4) Close the application, and install Impress version 1.03.062.02

5) Repeat the process of cancelling the download, reselect the file and restart the download.

6) You should see files in the earlier folder disappears and replaced with new files. If not, refresh the folder and wait for the "data" folder to appear.

7) Replace the PackageInstaller.zip with the one you copied before.

8) After the data files download completed, it will now automatically installs. Problem solved.

Hope this helps whoever needs it.

Can anyone shed some light on how to fix this issue?

We are supplying external A/V for an event at a hotel where the installed crestron system flashes a disconnected message and then causes the 2 roll down projector screens to roll up and the projectors to power down.

I should add that the projectors are receiving input signal perfectly.

Any suggestions or quick fixes?

My first instinct is to power down and re-start the crestron unit.

UPDATE: After the conference group left the venue, I managed to lower the screens, set all other crestron controlled systems where they needed to be (hotel lobby, fitness center, and gym audio levels) and unplug the CP3N so it will no longer send the power off and screen up commands intermittently. I am able to turn the projectors on and off via my flipper zero.

Thanks for all the support everyone! This community is great!

Howdy,

I have several DM-NVX-350's running 1.3547.00018. It looks like the proper firmware upgrade path is:

1.3547.00018 -> 2.1.3900.01115

After that, it looks like maybe 2->5->7?

I'd love to hear from someone who has some experience in a working path.

While I would never request the firmware in this subreddit, I will jump (slowly climb) onto a soapbox to say that any company gatekeeping firmwares for discontinued hardware kinda sucks.

Thanks all! Feels like there could be life left in these units if I can get them updated.

Best wishes,
John

Hi everyone!

I recently installed a DMC-STR into a DM-MD16x16-CPU3-RPS and I'm running into issues trying to get it going.

For some reason, I'm unable to push new network settings to it either through DMTool or using rcon through the text console. It seems to be stuck using 192.168.11.93 as it's IP and 255.255.254.0 as the subnet mask. Currently the only ethernet port being used is the LAN port on the CPU3.

Ideally I'd like the card to share the CPU3's LAN port and access an RTSP stream on that network. All of the documentation I've read points to this being a supported configuration. I tried configuring the card in DMTool to do this (setting port to "Internal" under ethernet options) although it seems the listed decoder IP address stays the same (192.168.11.93) and it's unable to connect to the stream. I have also tried using the content LAN port on both the CPU3 and the DMC-STR card with no luck.

I've also tried updating the firmware to the latest version. Currently the puf version I'm using is v3.04.16 with the DMC-STR firmware being v1.2911.00095 and the codec firmware version being v1.0002.00036. One interesting new issue that popped up after the firmware updates is that I'm no longer able to access the ethernet settings for the card from within DMTool. It just shows "Initializing, please wait..." and never actually initializes.

I have tried using `dmresetslot` to reset the slot, rebooting the card, changing the slot the card is in, and reflashing the firmware on the card. Still no luck.

If anyone has any ideas on what else I could try please let me know!

Thanks!

EDIT: Solved! See comment below

Hi

How are people getting used to the multi-page design concept (limitation) in Construct? My VTPro (and designs for other brands of touch panels) typically had one or two pages with lots of popups to deal with different scenarios - eg different source bars for different rooms, different transports for different devices, different lighting and environmental controls for different room types.. etc etc etc.

I just spoke to Crestron support and they said all I had to do was think about the project differently - where i previously had a popup - now I have a page.. but that really doesnt work.. you cant layer pages.. so if I have more than one source bar and more than one environmental controls page I cant combine them..

But what is the point of widgets if you cant use them? This seems like a real contradiction in design terms.

Is there likely to be a fix for this? And if not how are people changing their designs to manage this? From the top of my head I will need to do much more dynamic design on each page/widget..eg populating source bars using lists etc. That is fine.. but sometimes its good to just put a button where you want it from an aesthetic point of view.

Id be interested in your thoughts!

Thanks

James

thaanks for the insight

I have a project coming up, with a pretty fast turnaround time. I probably have 10,000 hours into VTPro-E. But I haven’t done any programming in the last four or five years. The thought of starting from scratch with VTPro E feels pretty daunting. I have experience with Web Front end, but I don’t have the time to build out my own framework and I want to give construct a shot. I’m wondering how everyone’s feeling on construct. What should I look out for as a newbie?

Lately I've been working on a project where I'm using the sACN module to control a set of DMX lighting fixtures via ethernet. So far it works as expected. But I was wondering if there was a module that will accept an incoming sACN signal so that a DMX console can control the lighting on the crestron system (for a completely different project)

My current work-around is to use a DMX to 0-10 converter which I wired into an SIM port and it does the job. But I was looking to make a more cleaner setup just by being able to use sACN/Artnet protocol coming from the DMX system into the crestron lighting control.

Thanks in advanced.

Hi all — my experience is SIMPL# and CH5, I have presumably not complex project to complete but must use SIMPL Win because of MPC3-302-B. I really struggle with SIMPL Win, hope more experience people here can help me a bit.

Setup: MPC3-302-B, SIMPL Windows. Camera control is PTZ, RS232, VISCA, 9600 baud, reached through a CEN-IO-COM-102 (its RS232-2 port). Preset recall only — no pan/tilt/zoom, no store, just recall preset 1/2 from two panel buttons.

I've got "Pan/Tilt/Zoom/Focus (cm)" placed and logically wired (Preset_1/2 inputs, feedback outputs) — but it has no tx$/rx$ or any connection parameter at all. No IP-ID, no COM port field, nothing. It looks like control logic only, expecting a separate transport/comm symbol underneath it — same two-piece pattern as the Biamp Tesira modules (Comm + Level Control).

Question: is there a standard VISCA transport/comm symbol I'm missing in the Crestron DB, or does this specific module need something else to actually reach a COM port? Also open to: is "Sony EVI-D100 1-Way Camera Control (6 Presets) (cm)" the better module to use instead — has anyone used that one specifically through a CEN-IO-COM-102 rather than a direct processor COM port?

Appreciate any pointers — happy to share more screenshots if useful.

I've been asked to assess a system that has a Crestron controller plus a few other Crestron bits (cinema remote, audio matrix and a ufh stat). Everything else in the system I'm familiar with but obviously it's not much use without the controller up and running. The original installer is out of the picture. I understand that the CP4-R is a few years old what are the chances that someone will want to take this on? What are my options here?
