Whatever I do I can't seem to upgrade the firmware from v2.1.8@bbbe9821+ on my Motion Sensor 2. I have tried
- The normal upgrade button
- Upgrade from url
- http://<Shelly_IP>/ota?update
- http://<Shelly_IP>/ota?url=<Firmware_zip_URL> using both archive and cloud
- Downgrade using url
Whatever I try, everything seems to fail and revert back to v2.1.8@bbbe9821+
Anyone that can help?
