pi_dht_webthing
A web connected humidity and temperature sensor
This project provides a webthing API to a DHT11 or DHT22 humidity and temperature sensor running on a Raspberry Pi. As a webthing, the DHT sensor can be discovered and used by home automation systems or custom solutions supporting the webthing API.
The pi_dht_webthing exposes an http webthing endpoint which supports reading the humidity and temperature sensor values via http. E.g.
# webthing has been started on host 192.168.0.23
curl http://192.168.0.23:8070/properties
{
"temperature" : 17.3,
"humidity" : 79.9
}
A RaspberryPi/DHTxx hardware setup and wiring may look like DHT22 example.
To install this software you may use Docker or PIP package manager such as shown below
** Docker approach**
sudo docker run --privileged -p 8070:8070 -e gpio=2 grro/pi_dht_webthing:0.1.0
PIP approach
sudo pip install pi_dht_webthing
After this installation you may start the webthing http endpoint inside your python code or via command line using
sudo dht --command listen --h--port 8070 --gpio 2
Here, the webthing API will be bind on port 8070 and be connected to the DHTxx signal pin using gpio 2
Alternatively to the listen command, you can use the register command to register and start the webthing service as systemd unit. By doing this the webthing service will be started automatically on boot. Starting the server manually using the listen command is no longer necessary.
sudo dht --command register --port 8070 --gpio 2
