That makes sense, though I have also spotted issues with one of my other Shelly devices: Shelly 1PM Gen3 + Shelly Plus Add-On + 5x DS18B20 temp sensors.
Homey does not update the read outs of the latter two sensors (4 and 5, or in Shelly’s web interface that starts counting at zero, 3 and 4). I can see in the device’s own web interface that the values of those sensors have changed, so it seems they are not communicating to Homey. If I restart the Shelly app on Homey then those values are updated after a while, but then get stuck again.
If I am correct Gen3 devices have not yet been added to your new Shelly app. So for now I am thinking if the better option is to revert back to the prior firmware version (1.7.5 and 1.7.99) on my Shelly devices. Not sure whether that is possible.
Firmware 2.0.0 is indeed a major release, so migrating to the new app will most probably be the solution there as well. Please make sure to email us so that we can note your request for the 1PM Gen3 in our ticket system. While we currently have priority on devices that are not yet supported, we will be adding the older Gen2 and Gen3 devices as well, and we will base their priority on their populairity.
Regarding the downgrade: I believe that should be possible if you have the firmware file. We do not have those available, so you will have to contact Shelly support for that.
I migrated one of the Power Strips 4 Gen4 to the new Shelly Control app: the issue of the device not or partially responding to switch commands in parallel has been resolved using that app. So that looks promising .
I also noted that you added more capabilities/sensors and also made available some of the settings, that were previously only available through the Shelly webinterface (like LED color and default state after a power loss), to the Advanced Settings in the device tile .
I have sent you a request via e-mail (#51) to add several Gen3 and Gen 2 models, including the 1PM Gen3, which is causing issues in combination with the old app after the new Shelly 2.0.0. firmware was installed.
