I was using Heiman Combustible Gas Sensor for some time with Homey 2019 pro (it didn’t work on newest [Heiman Aplikacja na Homey | Homey](https://homey.app/pl-pl/app/com.heiman/Heiman/) app). I was using older app from Github.

Things changed couple of days ago when I bought Homey Pro 2023. Old app doesn’t work (wrong SDK). New app adding Gas sensor correctly bu sensor do nothing (Gas alarm never trigers).

When I am testing connection in Homey Developer Z-wave tool everything seems to be ok. When I push test button on Gas sensor I see that Tx and Rx are received.

Maybe someone is using this sensor and Homey 2023 Pro and know what to do?

Best regards
