What’s in the box

1 x Smart Switch, 1 x English User Manual

Home automation compatible?

Out of the box the Sonoff is not compatible with platforms like Home-Assistant or Domoticz. Therefore, if you want to connect the Sonoff to those platform you need to flash it with custom software. We will write a tutorial about that in the near future. But we can give you a hint: easpesp or Tasmota.

However, it is compatible with Alexa en Google Home what makes the Sonoff very interesting for people who are into those platforms.

Our not so Review of the Sonoff TH16

So, we wanted to give you guys a full-blown review of this great device, but sadly we made an mistake. What makes the TH16 special is that it can be connected to a temperature and humidity sensor, where the values can be set as a trigger to switch on a device such as a fan. Sadly, the sensors are not included in the box and that was something we didn’t notice when we ordered the Sonoff TH16. As a result, we were not able to test the most important features of this device.

Therefore, we were just able to test it as a simple WiFi switch and for that we just can say: it just works like any other WiFi switch. Using the EWeLink app, we connected it to our WiFi network and to our EWeLink account and that’s really it.

So this ends our review of the Sonoff TH16 for now while we order a couple of sensors.
