This is my little smart rain sensor. I've seen a few of these knocking around on other sites, but thought I'd have a stab at one myself. The idea of that the device is to have a sensor for light rain and a sensor for heavier showers. It is designed to be fixed on a balcony railing.

The zigbee sensors used were tested on Home Assistant (Zigbee2mqtt and on a Somfy Tahoma Swith box)

There are 2 versions of the box, one without holes and one with holes to potentially evacuate water or humidity

Things you need to make it :
1- PCB rain sensor (HW-028) such as this.
2- Zigbee water leak sensor such as this
3- Zigbee water leak sensor such as this
4- Brass hot melt insert nut (M3 (OD 5mm) such as this

Print instructions
I printed all parts with PETG (resistance to sun and rain)
