Heating
Using
The G1, G2 and G14 heater thermostat can be set from the control panel or mqtt.
There is also central heating from Summerhall, which is switched on rarely. Panels are above the windows of G1, and above the test gear in G14. It can by adjusted with the knobs.
Implementation Details
The electric heaters in G1, G2 and G8 are controlled by multiple WiFi switched sockets. Room temperature is determined by the wireless sensor with DS18B20, LDR, and two AA batteries on the G1 table, the thermostat is a python script at ehl-vm-things:/srv/docker/py3scripts/scripts/thermostat.
Target temperature can be changed by MQTT Message Bus messages, which can be sent by the control panel in G1, or by your computer.
The plugs are MQTT devices which also monitor power usage. Heaters must be run on the lowest power setting to avoid exceeding the plug's safe switching capacity.
TODO
- Add temperature target charges to #things discord channel
- Put plug stats into Grafana
- Warn when the heater power is set too high and turn the plug off
