Well, I don't have any Cloud enabled devices. So, I manually upgraded my motion sensors.
Experience is not really excellent.
1. First, I had to manually reboot the Shelly Motions, so that they would see the update.
2. Updating took a considerable time, much longer than the usual Shelly devices.
3. After updating, I was unable to connect to the Shelly Motions, though they did work.
4. Reset a device is not straight forward anymore. Seems the device notices the reset button is pressed, but when you wait too long to connect to its own generated WiFi signal, it returns to the configured mode. In itself not a bad idea, but I didn't know about it.
5. Re-configuring the device is a snap, like it was before. Now I see time indicators next to the 'Action' URL entries. Apparently, one can program in that they only detect during a preset time interval. Like :
from 06:00 to 23:00
or something similar. Nice, but anyway, I left both to 00:00. I hope that is okay for them to always work.
6. After configuring, the device goes - without warning - into power saving mode. It's pingable, but the device only answers sometimes.
So, now I tried to connect to the device to access the web interface. >>impossible<<
Once the device is set up, the web interface loads a little bit (I tried 4 different browsers: Safari, Chrome, Brave and FireFox). But immediately (I suspect it goes to sleep) the loading is halted - for ever. I suspect the device after a small sleep does not remember I connected to it.
In short, after the device is set up, it works, but unable to get to the web interface anymore (the actions are done well, though).
Finally: I'll see if the device keeps sending its actions. I can't see the device status anymore, so I will rely on the actions to let me know it is okay. This is very similar to flood, door and other devices, that to save battery go to sleep. They become unreachable (unless the very short moment an action taakes place).
Let's hope for the best!
