Question about Netatmo Rain gauge

You need at least the basic kit for indoors

Hello, actually you only need the central module inside. But be careful, this is not the smart indoor module that you can buy here for 62.50. Unfortunately, I have never seen the central module for sale on its own. So you'll have to buy the Netatmo smart weather station for 141 to operate the rain sensor. Somehow that makes sense, as the rain sensor doesn't report the outside temperature or any other values. The rain sensor reports the amount of rain, i.e. mm of rain per time unit and nothing more. I hope that helps.
