Shelly Plus Add-On

Great device and very versatile. Quite simple to program via the app.

Shelly add-ons are great

This is a must have for anyone needing extra data or sensors. Super simple setup once you have read the documentation. I wish I had more data to collect.

Shelly Plus Add-On

I used the Shelly Plus Add-On along with the Shelly Plus 1. In total four were used in a commercial project where a grocery store need to monitor and send email alerts for 7 fridges, freezers including a walk-in-fridge & freezer. The system works very very well. Would recommend highly for especially in this type of installation. I'm happy to give free advice to anyone with setup questions.
