Simple temperature sensors to work with Tempest Wi-Fi Hub?

It’s great having the Tempest station, it works marvellously, but I need to extend my temperature readings to include greenhouses - and it’s quite an overkill to have another full station in there, both in terms of cost and features.

Question: are there any Hub-compatible simple temperature and humidity sensors I could use as addons to the existing installation, for example in greenhouses?

The WeatherFlow Air sensor is exactly what you are looking for…but unfortunately it (and the Sky wind/rain/sunlight sensor) were discontinued when the one-piece Tempest system was released. There may be a few floating around on the used market if you search.

Since you have greenhouses, I would suggest looking at a LoRa-based agricultural system for monitoring their internal temperatures/humidities instead of trying to find a bunch of old WF Air sensors…

You might look at the sensors and hub from SensorPush https://www.sensorpush.com/. I have found them to be extremely reliable. I even buried one to get ground temperature!
