Add sensors to your Shelly relay.
What it does
Shelly Plus Add-On clips onto a compatible Shelly relay and gives it sensor inputs. It takes up to five DS18B20 temperature probes or one DHT22 temperature and humidity sensor, plus a 0 to 10 V analog input and a digital input. It is galvanically isolated from the mains side and draws its power from the host device, so it needs no supply of its own.
With a relay underneath, the readings can drive the switching. A temperature probe can watch a cold room or the pipework of a geyser while the relay acts on the result, and a soil moisture sensor can hold back an irrigation pump until the ground is dry. Readings appear in the Shelly Smart Control app alongside the host device.
It works with the Shelly Plus devices and the Gen3 and Gen4 relays, dimmers and meters that Shelly lists, including Shelly 1 Gen4, 1PM Gen4, 2PM Gen4, 1 Gen3, 1PM Gen3 and 2PM Gen3. Check the full list in the specifications before you buy. Probes and sensors are sold separately.

Install
This device is wired into your mains or DB board and must be fitted by a registered electrician.
A registered electrician must fit the Add-On, because it attaches to a mains-wired relay. The sensor side is low voltage, and Shelly's official guide covers the connections.
