Power measurements

It could be very useful in automation to know how much power the pump uses currently when balancing with other high consumers in a house. It could also be log history in pump power consumption using a home automation system. 

Later heat pumps often has built in functions for power measurements. It can show how much energy the pump uses at this moment, and also store the summary of used energy and produced energy. Older heat pump are often missing this feature. For example IVT Greenline with Rego600, Some IVT Rego 800 and 1000 models and Thermia Diplomat. 

The power summary function in H60 works best for so called ”on/off pumps”. That means pumps with non variable, inverter controlled compressor. However it can work for inverter pumps as well with different levels of success.

To setup the measurements you must look up the manual for you heat pump and determine through is specifications how much power (Watt) each component draws. With components we mean Compressor, Pumps, Electrical heater, Heating cable, etc.
Click here to see if you can find the power usage for your pump at Husdata.

Then you enter this information on each component status variable in the H60 web interface. If a component has multiple variables, for example Additional electrical heat having both a status (on/off) variable and a percentage (0-100) variable, only enter the wattage on one of them not to summarize it twice.

When this has been configured you should see the summary of all active devices power usage in the top info dialogue.
The summary of currently used power can be accessed through MQTT or RestAPI for your home automation system.



For MQTT just the power info is part of the STATUS topic, so calling for status will return this value.
However it is also published automatically on every change, and can be set to refresh every X seconds using the ”MQTT_PUBALL” setting, set to number of seconds for republishing ALL data.

Example Homeassistant
sensor:
  - name: "Power usage"   
   
state_topic: "cc50e123fcdf/HP/STATUS/POWERSUM"
    unit_of_measurement: "W"
    icon: mdi:flash

For RestAPI just request Status and it will be part for the response.
