HoneywellHome/Resideo homekit integration PROA7Plus

rohit · June 27, 2025, 7:22pm

Hi HA community,

I am trying to integrate a HoneywellHome/Resideo security alarm panel PROA7Plus using the homekit device integration. I’ve tried this with HA running on a RPI5 and in VMware and am arriving at pretty much the same result. I am able to discover the device in HA, but as soon as I try to add it after putting in the pairing code, I get an error stating “Invalid flow specified”. Strangely, the panel itself shows “Success. ProSeries Controler successfully added as an accessory in Apple Home”

Some data from the logs:

    )

Appreciate any help on this!

In case someone comes across this issue and burns hours (or days) in frustration, this is what I observed:

For some odd reason, the PROA7Plus cannot be the first homekit device in HA
I added a Vizio TV that supports Homekit and it created a device in HA
I put the PROA7Plus in the mode to be discovered; after discovery by HA, I attempt to pair it and I have the same issue

5. I choose to click on “ADD ENTRY” and follow the same procedure of entering the homekit pairing code and it works like a charm:

I’m not sure what causes this, but hopefully this helps someone.

Hope this helps.
