homie-dht

MQTT Humidity, Temperature and Air Preasure Sensor Node based on HOMIE. Support DHT11, DHT22, BME280, SHT30 and SHT31. Optional use esp's deep sleep mode

Features

Configurable Sensor Type
Configurable MQTT Publish Interval
Configurable Deep Sleep
Configurable threashold to force acyclic sensor reading / publishing (publishKey and publishValue)
React on $broadcast/wakeup -> seconds, to prevent from going to deep sleep till seconds are gone
OTA Support (tested with jpmens/homie-ota)
Generic Sensor Interface to ease implementation of further sensor types

You can update the configuration on-the-fly by publishing incremental JSON updates to $implementation/config/set e.g. homie-dht/xxxxxxxx/$implementation/config/set -> {"settings":{"type":"sht31"}} You can force a factory reset by publishing homie-dht/xxxxxxxx/$implementation/reset -> true Keep the home-dht awake till seconds are gone, e.g. homie-dht/$broadcast/wakeup -> 5
