low cost weather station for openhab

[Arnold Maderthaner]

Hi !

I'm searching for a low cost weather station for openhab. At the moment I use the weather binding to retrieve local outdoor temperature,humidity,... values.

It would be great to also capture the same values inhouse but I'm struggling to find the best solution for that (ideally it could also measure the outside temperature so that I can get the real values).

I don't want to use netatmo or any other "cloud only" devices.

Any suggestions ?

You could use a simple 433Mhz weather station, like this one. You'll only need the sensor that comes with it. Then you'll need something to receive the 433mhz signal. I'm using pilight (with openHAB binding) with a cheap 433mhz transceiver on the Raspberry Pi, but you could probably also use an rfxcom (with binding). The last option is a bit more expensive though. Otherwise an Arduino with transceiver and ethernet shield would also be an option.

which 433mhz transceiver would you suggest as the rfxcom one is about 100€ afaik. ?
I'm currently running my openhab on ubuntu linux (on an Intel NUC) so running pilight shouldn't be a problem.

I bought this one on eBay which seems to work fine. With the NUC you'll probably need an Arduino Nano as well (see this documentation). You can also buy a complete kit at pilight.org.

Hello Arnold,

I developed a binding for Oregon WMR 88/100/180 weather stations. The binding runs well but documentation is only available in german language.
