Hello,
I think I am also affected by this problem.
In 2019 I bought 16 Shelly 2.5 and installed them (for shutters). Actually, they run well.
Just under a year ago, one Shelly started not working properly. It was offline again and again. Also no longer switch via the switches.
Shortly turn off the fuse, brought relief for a few hours (estimated max. 24h).
Due to this, I then exchanged it for a new one, because I thought I got a bad one.
But unfortunately, then followed at the end of last year another with the same problems. This could be switched then at least for a time via the switches.
And now just a few days ago is the 3rd followed. Offline, after fuse off/on again for a few hours online. If this is offline, it can also no longer be controlled via the switches.
Since the 3 are all independent Shellys, I do not assume that it has anything to do with the connection or the place where they are installed.
There is also a sound to hear.
I somehow have the feeling that you read more and more of it.
Then this is actually a defect, as mentioned in the post above. Is there no official statement from Shelly on this?
I do not know if I still have claims for the Shelly's from 2019 at my dealer, but obviously it affects exactly the batch, there will be more of the many to follow
