Good Add On

Worked great to add on temperature sensors to create a water circulation controller. Setup was very easy to configure. I wish it had a better locking mechanism to the shelly relay as the latch can get dislodged in a tight junction box. Would recommend for someone looking to add on capabilities with a turnkey device.

Such a simple add-on. Clip on and go.

Simple to add a DS style 1wire temperature device. Setup was straightforward. Reports as {temperature:100}.
