How to update the firmware on Shelly Wave devices?


try the shelly forum:

look under known issues:
→ Inputs of the Shelly Wave i4 are not updated

There is an issue with all firmware version prior to 11.x with the Shelly Wave i4 where it doesn’t register input changes. You will need to find a way to update the firmware of your Shelly device. Currently Zwave OTA updates arent supported by Homey. A possible solution is to setup ZwaveJS2MQTT with an external Zwave stick and update the device from there.

try if this maybe works!

(i just orderd my zwave usb stick to try to do above)
