Actual working temperatur

Hi !

I was browsing through the forums and found multiple reports of people having high temperatures on their shelly dimmer 2s. So I checked mine (which you can do by accessing this address http://%7bip of your dimmer}/status ; then find "tmp" and behind that there is temperature values in celsius and fahrenheit) and I have 46* C with lights off and 57* C with lights on.

Now this seems quite low compared to the reports here in the forum about reaching 105* C and such. It seem pretty high though compared to the Specifications mentioned in the 2-pages manual. There it states: Working temperature: from 0° C to 35° C.

Does anyone reach such low values?

What are your temperatures?

Working temperature means ambient temperature. The measured temperature is the temperature on the PCB inside the chip.

That'ld explain the low working temperature mentioned in the manual..

So what are reasonable temperatures of the dimmer? Is it just "everything below 105° C is ok" ?

Guzzi-Charlie

The reported 105°C should not be possible. Normally the Dimmer should switch off at >95°C. Normal operating temperature should not be higher then 70-85°C (reported from the Shelly inside the chip on the PCB).

I have two Shelley Dimmer 2, which are sitting behind a switch. They sometimes reach 69°C. The other two, which are in the distribution box are at 57°C max.
