Hello,
I have a Shelly 2.5 on my roller shutter and it worked fine until the latest firmware update. Now it has lost connection and I can’t get it to find the network anymore (every other wifi appliance in my house works just fine). The device is offline and I would like to know how to fix this problem. Thank you in advance!

Hi, difficult to to say what caused devices to go offline, but I have many 2.5s as shutters running on latest firmware 20200827 v1.8.3. with no issues. There are many reasons for offline issues, often due to weak signals or devices like repeaters kicking out, etc.
Here’s what to do if you want to start from scratch:
1) delete the device in the APP
2) turn the fuse giving the Shelly power off and then on again
3) reset the 2.5 by switching the shutter switch on/off 5 times (you’ll hear the Shelly Relais click on 5th switch) - check in the App if it’s online again
4) look for the 2.5 on your WLAN list and connect to it
5) go into you browser WEBUI and type in 192.168.33.1; you should see the Shelly
6) give it a static IP address outside DHCP router range 192.168.178.xy
7) connect to router WLAN again, the start Shelly app (discovered devices should come up)
add by IP if discovered devices doesn’t show
