Hello,

I have Heimann Smoke Senors HS1SA-M with Firmware-Version 1.0.  
Homey wants to update to version 1.7. After updating status is 100% an the device will rebooting, the update process aborts.

Does anyone have an idea? Thanks

Are you sure that it’s the Heiman device? The Heiman app didn’t have any updates for 3 months now, I don’t think it has OTA support.

It’s Matter over Thread 😉

@Thomas_Pietzschmann could you try placing the device as close to Homey, or your Thread Border Router, as possible during the update and see if that works?

I placed the smoke detector right next to the Homey during the update process. Unfortunately, without success.

There appears to be a problem with updating directly from version 1.0 to higher versions. Intermediate steps seem to be required.
