# pi_dht_webthing
A web connected humidity and temperature sensor
This project provides a [webthing API](https://iot.mozilla.org/wot/) to a [DHT11 or DHT22](https://learn.adafruit.com/dht) 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](docs/layout.png).
To install this software you may use [Docker](https://phoenixnap.com/kb/docker-on-raspberry-pi) or [PIP](https://realpython.com/what-is-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
```
