Hi,
After a firmware update my shelly 2.5 became slow and unstable. Sometimes it disappears from the wifi and if I reset it the direct connection from the pc also responds slowly on the web interface.
So I would like to make a complete recovery of the firmware, I have read the threads on the forum but I do not have access to the recovery page, what can I do?
Thx
Seems like there are lots of problems with the new firmware, mine can't be accessed at all, Reseting the device won't work either, Default Wifi is only available for seconds, too short to acces.
This might be of some help. I have similar problems with the latest 1.11.7 on my 2.5 where the WebUi is laggy and causing it to frequently reboot. I don't have a comparison point of when it "used to work" as this is my first 2.5 device. That said, I just downgraded via the Firmware Archive tool to 1.9.4 and I am no longer seeing my web UI lag/reboot issues. Hope this helps for you.
Same issue here, device seems to work at first but after a short time the MQTT events bevome unreliable and the UI becomes inaccessible.
(seemed to be mostly when turning on both connected lights, the state of the second light will not get updated and it goes downhill from there, not sure if that has anything to do with the issue or if it is just some timing related issue)
Tried factory reset, tried disabling eco mode, no change.
Device is configured as relay (other 2.5 devices in network are configured as roller/shutter and don't show the same issues)
Network is a mesh network (AVM/FritzBox)
Cloud connection disabled, coloT disabled, MQTT enabled
A downgrade to 1.9.4 seems to solve this. (though I have no AP roaming with the old version...)
Update: While writing this i thought maybe the AP roaming is the issue. So I updated the FW yet again to 20220209-093016/v1.11.8-g8c7bb8d but did not enable AP roaming. Until now it seems to work even with eco mode on (fingers crossed)t
Update 2: Issue is back again, crappy MQTT and http connectivity. will try now to see if 1.9.4 is long-term stable. .
I have the exact same issue. It's the only 2.5 I've got as a light switch and the only one (I have 10 others as covers/blinds) and the only weirdly behaving one.
