There is temperature ramp prepared which controls the heating power of all four heaters between 0 and 100% depending on the Temperatur read on C1.

Run inside a screen session:

/home/pi/python/actor/actor.py

Code can be found here: https://gitlab.rlp.net/bes3-mainz/mogon-testbench/snippets/497

HINT: Better use the web interface to get the status and set the heaters power: http://localhost:10001/status.php#page1

Control the heaters be writing them a value in the range 0.00 and 1.00:

mosquitto_pub -h mould-control -t 'homie/fsrcontrol/heater/dimmer<Dimmer ID 1..4>/set' -m <brightness 0..1.0>

Example:

mosquitto_pub -h mould-control -t 'homie/fsrcontrol/heater/dimmer4/set' -m 0.75

Get the status

mosquitto_sub -h mould-control -t 'homie/fsrcontrol/heater/dimmer1' -t 'homie/fsrcontrol/heater/dimmer2' -t 'homie/fsrcontrol/heater/dimmer3' -t 'homie/fsrcontrol/heater/dimmer4' -v

Switch on all 4 heaters:

  mosquitto_pub -h mould-control -t 'homie/fsrcontrol/heater/dimmer1/set' -m 1; 
  mosquitto_pub -h mould-control -t 'homie/fsrcontrol/heater/dimmer2/set' -m 1; 
  mosquitto_pub -h mould-control -t 'homie/fsrcontrol/heater/dimmer3/set' -m 1; 
  mosquitto_pub -h mould-control -t 'homie/fsrcontrol/heater/dimmer4/set' -m 1; 
  echo "done"

Switch off all 4 heaters:

  mosquitto_pub -h mould-control -t 'homie/fsrcontrol/heater/dimmer1/set' -m 0; 
  mosquitto_pub -h mould-control -t 'homie/fsrcontrol/heater/dimmer2/set' -m 0; 
  mosquitto_pub -h mould-control -t 'homie/fsrcontrol/heater/dimmer3/set' -m 0; 
  mosquitto_pub -h mould-control -t 'homie/fsrcontrol/heater/dimmer4/set' -m 0;
  echo "done"
