    Hello
    I am a beginner
    This mqtt data is taken with MQTT-Explorer

    {"id":0, "source":"init", "output":true, "apower":0.0, "voltage":231.4, "freq":50.0, "current":0.000, "pf":0.00, "aenergy":{"total":0.000,"by_minute":[0.000,0.000,0.000],"minute_ts":1761640320}, "ret_aenergy":{"total":0.000,"by_minute":[0.000,0.000,0.000],"minute_ts":1761640320},"temperature":{"tC":65.7, "tF":150.3}}

    the shelly is Shelly2PMG3-B08184F41CDC
    it is in eco mode
    the internal temperature of the Shelly is very high(65.7)
    there is no ampere, there is nothing conected to it
    why is the internal temperature so high?

    Firmware ID: 20240731-123728/1.4.99-2pmg3prod0-ge3db05c

    can I do something to lower that temperature?

    In other Shelly's I already uploaded the latest firmware and I couldn't reduce the temperature

    thanks for reading me

    This temperature seems a bit high for my taste. How is this Shelly 2PM Gen3 mounted? Or is it still "on the table"?


    I had/have the problem with "higher temperature" (but only ~10°C) with the following combination:

    - Shelly Plus 2PM (=> device is not that relevant)
    - ECO mode is active
    - Bluetooth Gateway is active
    - Home Assistant uses Shelly device as Bluetooth Gateway

    => HA "activates" a script at the Shelly device which results in a higher CPU utilization whitch causes the temperature increase. But even with this combination the max. temperature at my devices was <50°C in the summer. But this depends where you placed your devices.

    This behavior can also occur if you have a high cpu usage for some other reason.

    Zitat von tvbshelly

    I think it is a good idea to update the firmware first.

    But he already told us that a firmware update did not solve his problem
