Documentation about the protocols of ELV Mobile Alerts sensors plus a node MQTT gateway

This document tries to describe every detail of the Mobile Alerts sensors, which are sold by ELV in Germany, but are also available at the common suspects (Amazon, etc). Be careful buying at Amazon: certain sensors mention Mobile Alerts, but seem to be designed for the US. They are not compatible with the ELV Mobile Alerts ones!

Mobile Alerts is covering mostly climate sensors, but also contains moisture and door/window sensors plus a sound detector, which acts as a gateway for smoke sensors.

The Mobile Alerts are a version of the LaCrosse Alerts Mobile system made for the European market.
