I have had a Shelly 2.5 installed, Home Assistant shows its internal temperature as 55 to 60 degrees with no load. With a temperature of around 70 degrees with a load on both relays.

Compared to Shelly 1pm which run at 1/2 the temperature.

What internal temperatures do your Shelly 2.5 show?

Mine isn't installed yet, but show internal temperature of 36 degrees C with no load. I use ESP home on it, and had to toggle GPIO16 otherwise temperatures would be WAY higher:

binary_sensor:
- platform: gpio
pin: GPIO16
name: "ade7953 IRQ pin"
internal: true

This article details the fix: https://savjee.be/2020/11/shelly25-esphome-potential-fire-hazard-fix/

Fix might be needed for other platforms, but shouldn't be needed for standard Shelly firmware.

I'm seeing it slowly dropping down to 55C overnight, and up to 75C with both outputs on. Interestingly, I can clearly see when each output is turned on/off (it changes temperature by ~10C)
