Resideo/Honeywell ElitePRO S900/S1000/S1100/S1200 — what does Matter expose to Home Assistant?

I’m considering an ElitePRO S1000, primarily because I want to monitor and log my HVAC locally with Home Assistant without depending on Resideo’s cloud.

Has anyone paired an S900, S1000, S1100 or S1200/X8S directly with Home Assistant using Matter? If multiple models have been tested, comparisons would be particularly useful.

Could you post a screenshot or list of the entities/attributes HA creates? In particular I’m interested in whether Matter exposes:

  • current temperature
  • current humidity
  • HVAC operating state (idle/heating/cooling)
  • heat/cool demand or call state
  • current heating/cooling stage
  • fan state
  • humidifier state
  • any RedLINK remote-sensor data (S1000/S1100/S1200)

I’m specifically asking about the local Matter integration, rather than the Resideo cloud API.

@sfcodes — tagging you since your ha-resideo work on the S1200/X8S shows that the thermostat itself has a much richer set of telemetry available through Resideo’s backend. Have you also paired your S1200/X8S to HA over Matter? I’d be particularly interested in what subset of that data Matter actually exposes.

My basic objective is fairly simple: I want HA to record indoor temperatures and actual heating/cooling calls so I can correlate HVAC runtime with outdoor temperature and independent room-temperature sensors. I’m trying to keep the core logging system functional without Internet access or vendor cloud services.

I just got the s1200 installed today with a new furnace and heatpump. I set up the main app, First Alert by Residio, and the amount of control in the app is underwhelming.

It linked to Home Assistant over Matter without any issues. From the device touch screen, go to Menu, swipe to the next page, then choose Matter to show the QR code.

For control, it exposes heat and cool points, along with a mode selection (Heat/Cool, Heat, Cool, Off). The only sensor exposed is temperature, even though the native app shows humidity. Configuration options is limited to temperature display units. The diagnostic outputs are uptime and reboot count.

I’m posting this from mobile and the image upload is not liking me. I’ll try and post screenshots when I’m at a computer.
