Humidity Sensor Addon? #292

Closed malgates closed 5 months ago

malgates commented 1 year ago

Hi everyone,

is it possible to add a humidity sensor to the ESP? Does not need to display it via the display. But sharing the info via MQTT would be great!

I am just thinking about integrating a DHT22 temperature/humidity sensor. There should be enough space on the BHT002 board for the sensor. It could be attached to a free GPIO of the ESP module. The WThermostatBeca-software could altered including the DHT library and handling the signal similar to the GPIO5 relay input (optional switch in configuration, serve value via MQTT or webthings). Looks quite simple but I am not got enough in software to do that fast.

I would love to add a humidity sensor to the ESP, as well!

andreasz70 commented 7 months ago

I added a few lines to the source code:

include DHT.h library,
init dht object,
add a checkbox to the web-config
add a few lines to activate the humidity property and modified the hardware to connect a DHT22 sensor to GPIO 4 (tested without the BHT002 connected)

For details see https://github.com/klausahrenberg/WThermostatBeca/pull/322

How dows the Hardware mod look like? How can I test it?
