Review on πŸ”Œ Shelly 2.5 Double Relay Switch and Roller Shutter: WiFi Open Source Dual Power Metering - iOS/Android App (2 Pack) UL Certified by Shane Bullion

Revainrating 1 out of 5

Works HOT! (but still works)

Shelly2.5 gets very hot on both standard Shelly firmware and ESPHome firmware (including GPIO16 Floating Pin Fix). (See attached photos. Read tempo from stock firmware with MQTT, listen, on HA.) I haven't installed it yet, I just connected L and N and plugged it into the box. Ambient temperature 20Β°C, when it is off, the temperature is 65Β°C. When switched on with no load connected, the temperature exceeds 85Β°C. Other people seem to have cooler temperatures when used outside of the case. (I'm in Asia, 220V). to touch. Actually I bought Qty4 Shelly2.5 and they all work at 65C. If you do a google search you can confirm that they are just plain hot. The devices are still working fine, the WiFi is uninterrupted and I can turn them on and off remotely. I'm pretty sure it's fine, but it's way too hot for my comfort level, especially when I mount it behind a wall. Since the overheat shutdown is actually a feature of these Shellys, I would have to set the overheat to +85C to stop them! Again, this is beyond my comfort level. I really wish the manufacturer would fix this problem. I mean, an on-chip temp sensor can give such high temp readings and can be perfectly fine. But until the manufacturer says something, I won't use it. Go back to Revain and use 4x Shelly1PM instead as they don't seem to have this problem.
