USB-thermometer RODOS-5Z As a Service.

Here is example how to use USB-dongle RODOS-5Z with MP707 sensor to control indoor temperature and visualize it with web-based services like Grafana+InfluxDB.

1. Configuration on remote host (aka web-server):

• Copy service/server to server
• Install docker
• Configure env section in docker-compose.yaml for both services grafana and db
• Create services and start them: docker-compose up -d grafana db
• Okay, now your server is ready to receive data: there is listening influxdb-service on port 8086, which recieve data from client and grafana-service which visualize that data

2. Configuration on Host with RODOS connected:

• Put udev-rule 99-rodos.rules to /etc/udev/rules.d to set correct rights to access the dongle.

• Compile bmcontrol or use compiled version.

• Check that bmcontrol works normally:

./bmcontrol scan
sensor 1 = ca031761d4daff28

./bmcontrol temp ca031761d4daff28
27.543

• Copy service/host to your host with rodos connected

• Set you sensor id with SENSOR_ID var in service/engine/engine.py

• Configure engine-service in docker-compose.yaml to be able to connect to database (db) on remote host

• Create and start service engine: docker-compose up -d engine

• Okay, now your service gets temperature and writes it to InfluxDB on remote host

• Go to http://office_temp.your.site:3000 (or whatever you have server configuration is...) and configure Grafana to visualize data from database:
