influx4mqtt

Insert incoming MQTT values into InfluxDB.

see https://github.com/mqtt-smarthome/mqtt-smarthome

Removes the mqtt-smarthome status from the topic (e.g. hm/status/lamp gets replaced by hm//lamp). Inserts numeric value only to InfluxDB, booleans are converted to 0.0 respectively 1.0. Strings are ignored.

Install & Usage

$ sudo npm install -g influx4mqtt

I suggest to use pm2 to manage the influx4mqtt process (start on system boot, manage log files, ...)
