homebridge-mqtt-temperature-log-tasmota

Plugin to HomeBridge optimized for work with Itead Sonoff and Electrodragon Relay Board hardware and firmware Sonoff-Tasmota via MQTT with log temperature (periodical and 24 h min. and max.) to file. It acts as a themperature monitor for DS18B20, DHT22, DHT11, AM2301, AM2302 sensors. Also works with other accessories sending the temperature as a number (payload ex. 21.1).

Like this? Please buy me a beer (or coffee) ;-)

sonoff in topic - topics name of Your Sonoff switch.

"topic" - telemetry topic (for sensors data)

"activityTopic": "tele/sonoff/LWT" - last will topic for check online state.

"activityParameter": "Online" - last will payload for online state.

"startCmd": "cmnd/sonoff/TelePeriod" - command sent after the connection.

"startParameter": "60" - payload for startCmd.

"pathToSave":"/root/.homebridge/" - path to save text files with temperature data.

"savePeriod": "15" - period (minutes) for saving and check temperature. For save only min. and max. 24h temperature data set with "minus" ex "-15". Minimal preriod 10 minutes. Empty: save every hour.

"zeroHour": "23" - time (UTC) at which you want to reset the timer min./max. Empty to reset after 24 hours since the last minimum or maximum.

"writeMinAndMax" - only write the log file, no min and max.

"singleFile" - write a _log.csv instead of separate files for temperature, pressure and humidity.

The files will be saved in the specified path with the "topic" (ex. Sonoff) in the file name ex. "/root/.homebridge/sonoff_temp.csv".

"sensorPropertyName": "BME280-2" - custom Property name for sensor (see accessory WWW console for tips: {"Time":"2017-03-01T08:47:19", "DHT22-2":{"Temperature":4.6, "Humidity":71.7}})
