Meross MS605 Compatible/Incompatible?

The Meross MS605 is listed as a compatible device, but I have had no luck adding to my C-8Pro v2.5.0.135 system. The device commissions with my Google Home Wifi Pro router (it is the Thread Border Router). I can generate a pairing code. The Meross device begins to flash orange when I submit the code, but nothing ever appears in the Matter log file and there is an immediate "Pairing failed @ ReadCommissioningInfo with code 202 (Interaction Model Error)" error. Any ideas? Any success elsewhere?

Do a factory reset on the device, remove it from google and pair it directly with hubitat

@andy16, I had a thread in beta section for this issue, as a workaround, you can roll back to software version 2.4.3.xxx - pair the device using Matter code as normal then update to latest software release again.

I was heartened to read the release notes of v2.5.0.143 and v2.5.0.157 with a possible pairing fix for Matter devices and then additional refinement in 157, but it was not to be for my MS605. I factory reset the device. Added it back in through documented method, generated a pairing code and added it to Hubitat. Same issue. Anyone else have any luck? I am currently on a C-8 Pro on 2.5.0.157.

Did you resolve your issue?

No. The issue is still unresolved for me.

Issue fixed in beta software v2.5.1.124.

I concur. I was able to add the device on 8/1/26. I forgot to note the version that I was on, but it somewhere north of the v2.5.1.124 referenced here. @iEnam My device adds using the Generic Matter Motion/Light Sensor driver, so I only have the device with information in the Current State fields plus the two zones with their info. I note from your screenshot that you are using a different driver. Is there a more appropriate driver to use for the MS605 Matter sensor?

Yes, the device correctly picks up the system driver and your ready to go, so no need to change if it's working well.

It is just my preference and have I been testing and using the "Matter Advanced Bridge" community driver for all my Matter devices since beta development.
