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"

  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;
