A thermometer / hygrometer for our home automation boxes

Orvibo ST30

Orvibo - ZigBee temperature and humidity sensor

Always knowing the temperature and humidity is a very French passion, it seems. A passion that has reached many home automation users. the Orvibo ST30 temperature and humidity sensor allows users of Jeedom or Home Assistant to know in real time, the temperature and humidity of a room.

With a digital screen, the information can be viewed without having to connect to the Home Assistant interface. It communicates via the Zigbee protocol, which we really appreciate and, thanks to it, you will be able to create multiple automations, to manage your heating, air conditioning and VMC ...

Orvibo ST30: installation and use on home automation box

We tried to introduce this thermometer to theAmazon Echo Plus 2nd generation which has a ZigBee bridge. Without success, Alexa fails to detect it. For Jeedom, this device is compatible with the Zigate plugin and the official Zigbee plugin from the Jeedom team via Zigate and Conbee II dongles. It is also compatible with the box Eedomus +, provided of course that you have added the ZigBee protocol.

As far as we are concerned, we have opted for the environment that interests us the most: Home Assistant. Pairing is carried out thanks to the ZigBee ConBee II key, and the add-on deCONZ.

On Home Assistant via deCONZ

  1. Log in to fromCONZ.
  2. Then go to " sensors " and start a search.
  3. Long press the small button above the thermometer and in a few seconds, the device is operational.

Strangely enough, we don't see the entity in the CONZ add-on, but when we go into Configuration> Integration> deCONZ> Devices, the entity is present. We had observed the same phenomenon for the light detector Xiaomi Mi Light Detection Sensor.

Rename the device to find it better.

Three entities are available as you can see:

  • humidity
  • Temperature
  • Battery level

You are ready to create your automations, charts, etc ...

Our opinion

Small but sturdy, the temperature and humidity sensor Orvibo ST30 is very easy to set up, elegant, efficient. In addition, the ZigBee is a major asset. This little round thermometer makes us think a lot about the Xiaomi Bluetooth that we use. We have also compared them. The little rod that allows you to put it down is nothing, but you had to think about it and we really appreciated it. We have nevertheless noticed that, on this model, the lifts are not regular. We were unable to determine the trigger for an ascent, sometimes ranging from 2 minutes to 2 hours, despite very minimal variations in temperature. However, Home Assistant will still show the correct value, but not as instantly as the Xiaomi Bluetooth models which meanwhile go up every minute. Maybe a smarter algorithm that will save batteries better? Let's hope so ! The ZigBee Orvibo ST30 sensor is available at Around € 27 at Domadoo.
Passionate about technology, I discovered the world of Smart Home with Xiaomi, then Alexa and Les Alexiens led me to become passionate about Home Assistant, which I master better every day!
