Shelly Pro4PM keeps going offline

    I am controlling my device over MQTT.

    Problem: It keeps going offline all the time.

    When I just leave it running and monitors the status messages arriving on MQTT, it goes online and offline around once per minute.

    If I send a relay actuation command over MQTT when it reports to be online, it immediately goes offline and does not actuate the relay.

    Firmware version

    Device ID: 083AF27C949C

    Firmware version: 0.10.3

    Firmware build ID: 20220617-111715/0.10.3-g7c89a05

    Web build ID: 1.5.5-b3d94f1

    Is my Shelly defect?

    Does the router have some "energy savings" mode that turn off Wifi / sleep at times? At least to check, I would try to connect the Pro 4PM via LAN-cable instead. If the problem disappears, Wifi is the culprit.

    All the best!
