# pi_awning_webthing
A web based patio awning control on Raspberry Pi.

Currently supported are [TB6612FNG powered](https://www.pololu.com/product/713) motors as
[DGO-3512ADA](https://www.ebay.co.uk/itm/Gear-Motor-Direct-Current-6-12V-Electric-With-Removable-Crank-DGO-3512ADA-/183375290396).
The specific motor configuration(s) are defined using a configuration file as shown below.
```
# name, gpio_forward, gpio_backward, step_duration_in_sec
lane1, 2, 3, 0.5
lane2, 19, 26, 0.5
lane3, 5, 6, 0.5
lane4, 10, 9, 0.5
```
For motors with TB6612FNG, the file name must contain the term *tb6612fng*, e.g. tb6612fng_motors.config. Concerning the
hardware setup and wiring please read [Example Hardware Setup](doc/dgo-3512ada.md).

To install this software, you can use the [Docker](https://phoenixnap.com/kb/docker-on-raspberry-pi) or [PIP](https://realpython.com/what-is-pip/) package manager as shown below

**Docker approach**
```
sudo docker run --privileged -p 9500:9500 -v /etc/awning/:/etc/awning/ -e filename=/etc/awning/tb6612fng_motors.config  grro/pi_awning_webthing:0.2.0
```

**PIP approach**
```
sudo pip install pi-awning-webthing
```

After installation, you can start the Webthing http endpoint in your Python code or from the command line by typing
```
sudo awning --command listen--port 9500 --filename /etc/awning/tb6612fng_motors.config
```
This binds the Webthing API to the local port 9500.

As an alternative to the *list* command, you can also use the *register* command to register and start the webthing service as a systemd entity.
This will automatically start the webthing service at boot time. Starting the server manually with the *listen* command is no longer necessary.
```
sudo awning --command register --port 9500 --filename /etc/awning/tb6612fng_motors.config 
```

The awning service provides an http webthing endpoint that supports the awning properties. E.g. 
```
# webthing has been started on host 192.168.0.23

curl http://192.168.0.23:9500/properties
