Hi, I have a problem after the last update of Shelly 2.5 on : 20210323-104714 / v1.10.1-gf276b51. I have 9x shelly 2.5 in the house, of which after updating 3 shelly have the status DEVICE IS DISCONNECTED, connection and power supply is OK, other shells work without problems. After removing from the application, resetting and re-adding the shell to the application for a while it works and then again has the status of the device is disconnected. Would you help me where the error might be?

Hi and welcome to the forum.
Try a downgrade using our firmwarearchive.

I have the same issue, 2x of my 3x Shelly 2.5 are showing as offline, they worked perfectly for about a year.
Is there a way to downgrade without removing them from behind the wallswitches?

Try ping.
If reachable --> yes.

Unfortunately they were not pingable anymore.
I just used this solution below and it worked.
The Shellies that had issues still showed Firmware 20201128-102046/v1.9.2 my Shelly that worked was already on v1.10.1.
I now upgraded all to v1.10.1 and see what happens.
Could be that they got stuck during firmware upgrade?...
My Solution:
(1) Disconnect the power from the Shelly by turning off a breaker or other means.
(2) Restore power.
(3) Within the first minute, toggle a switch connected to the "SW" input on the Shelly 5 times on/off (10 total) or press and release momentary button 5 times. -
