Rainmeter for Home Assistant

Description
=========

This rainmeter is meant to connect to Home Assistant using an Aqara door sensor over ZigBee.

You need:
Print the parts
1 Aqara door sensor
1 neodymium magnet 12x2mm

Print the parts and assemble them using a piece of filament as hinge, cut that piece long enough to not be able to slide out. Position the Aqara door sensor as in the picture. Or try what position works best. I would prefer to use the Aqara magnet that is supplied with the sensor, but it is a bit too heavy.

Calibration
========

Slowly pour, drip, 78ml (78g) of water through the funnel and count the times the cradle flips, you can hear it. This corresponds to 10mm of rain. Divide 10 by the amount of flips, this is the amount of rain in millimeter per flip. In my case I had 19 flips, which means 0.5263 mm of rain per flip.
