Geyser PRO – Home Assistant Add-on
Hi everyone! I'd like to share an add-on I built to integrate the Stocker Geyser PRO
mosquito repellent system into Home Assistant.
The Geyser PRO is a professional outdoor nebulization device used in gardens,
courtyards and public spaces. It didn't have any local API or official HA integration,
so I reverse-engineered the cloud app and built this bridge.
What it does
Full MQTT autodiscovery — all entities appear automatically in HA
Real-time status — battery, tank levels, next treatment, sync time
Strategy & cycle management — create, toggle and delete directly from HA
Multi-zone support — Zone 1 and Zone 2 independently
Quick Start — trigger instant nebulization with custom tank/zone/duration
Weather automation — built-in webhook support for IFTTT (wind, rain, clear sky)
Custom dashboard panel — dark-mode HTML panel included
