Domotik is a very simple home-automation software.
Originally, I've bought an Envi CC128, one Raspberry Pi 1 and I've used measureit to display my power consumption. It was fun but charts were cheap and difficults to upgrade.
Early in 2015, i discovered ESP8266 chip, Arduino UNO and IoT stuffs (like MQTT). I've decided to build my own devices…
I've took a comm' module from an Oregon Scientific Clock and plug it on a arduino board in order to receive data from an external temperature sensor thgr-511 (and that worked!)
Boosted by this success, I build several other temperature sensors.
In 2018 i received a Linky and decided to extract data with a Raspberry Pi Zero.
I've also built a webpage to display data to my TV.
This dashboard was firstly displayed thanks to an original Raspberry Pi 1 and recently on a Kindle Fire TV.
Server side, i've written several small scripts in Python using Mosquitto and Mongodb. Basically, everything was running on a raspberry pi 0/1.
- In 2015, i start the project on raspberry pi,
- In 2017, i switched on an x86 computer and Docker,
- In 2020, i replaced my raspberry-pi "TV" by a Kindle TV Stick + Fully Kiosk,
- In 2022, i gave up influxdb and built a dedicated datastore (based on golang and sqlite).
- In 2023, domotik works on a raspberry pi 0/1
> mkdir domotik
> wget https://raw.githubusercontent.com/sylvek/domotik/master/docker-compose.yml
> docker compose up
> #open http://localhost:3000 for the TV show
> #open http://localhost:3333 to display Grafana
> #You can simulate data by using [`mosquitto_pub`](https://mosquitto.org/man/mosquitto_pub-1.html).
> mosquitto_pub -h localhost -t sensors/outside/temp -m 4
> mosquitto_pub -h localhost -t sensors/linky/watt -m 4000
> mkdir /home/pi/domotik
> wget https://raw.githubusercontent.com/sylvek/domotik/master/docker-compose.armv6.yml
> docker compose -f docker-compose.armv6.yml up
Basically i use 3 temperature sensors and a "watt meter".
| name | topic | unit | usage |
|---|---|---|---|
| outside | sensors/outside/temp | xx.xx °c | a value every 10 min |
| living room | sensors/living/temp | xx.xx °c | a value every minute |
| room | sensors/room/temp | xx.xx °c | a value every minute |
| power consumption | sensors/linky/watt | xxxxx | a watt-hour value every second |
| power consumption | sensors/linky/indice | xxxxx | watt consumed since the first day |
| power state | sensors/linky/state | 1 or 0 | state between high and low tariff |
| service | link |
|---|---|
| tv dashboard | http://your_ip |
| pc dashboard | http://your_ip:3000 |
| MQTT broker | tcp://your_ip:1883 |
I use Grafana (plugged on SQLite) to display more dashboards. (look extras/grafana-save folder)
