      ## Zone 2, If you have 2 zones on the heatpump enable this:
      # esphome/.procon.zone2.yaml
      #
      ## Climate sensor, only heating (curve, room, flow) is supported at the moment with zone_1:
      # esphome/.procon.climate.yaml
      ## you need to add extra code homeassistant/automations_climate.yaml your automation.yaml in HA directory
      ##
      ## Measuring power and energy
      ## EASTRON 3ph SDM, If you have a 3phase Eastron kWh meter on the heatpump enable this:
      # esphome/.procon.sdm.yaml
      ## set parity to none on the kWh meter. Baudrate to 9600
      ## FINDER 1ph 7E 64 8 230 0210. If you have 2 of these kWh meters on the heatpump enable this:
      # esphome/.procon.finder.yaml
      ## set parity to none on the kWh meter. Baudrate to 9600
      ##
