    Raised a ticket with Shelly Support.

    They sent me a firmware file and told me to recalibrate.

    Managed to load firmware manually using pins which did bring the dimmer back to life.

    But whatever I did the leds got stuck on at about 40% with or without a calibration. You couldn't dim or switch them off.

    Support agreed it was faulty. Asked me to send it to them in Bulgaria. They would refund postage and send me a voucher for a new unit with free postage.

    Contacted my Uk supplier who offered a replacement or refund. I took the replacement which I have installed this morning. So far it is behaving as it should.

    I now have exactly the same as you.

    I went through exactly the same process.

    OTA upgrade went ok to latest. But then dimmer was erratic. Would switch lights on and they would go straight off again. Would switch lights on and couldn't switch them off.

    Power cycled the dimmer. Shelly AP came up but when I opened the IP address I received an error message "forbidden" on the web page.

    Factory reset did not work. Manually flashed latest firmware using NodeMCU pyflasher. Says its complete but the dimmer has no response, no led, nothing.

    Madgino did you raise a ticket?
