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
