Yes, that is what I plan to do. Sadly most of the Templates I found didn’t work due to Syntax Changes in HA, but I will get there eventually. I am going to test my current Automation for another day or so and play with some variables like the “Charge from Grid” and “Forcible Charge” options for my Inverter.
How have you found the DETA outdoor plugs? That was what I was looking at installing for my pool pump and heater.
Also with the move the EMHASS did you add any energy monitors to dynamically get the deferable load values or have you found they are pretty static and can just be approximated with a nominal values?
The Deta sockets have been pretty solid. They were a bit of a pain to setup with localtuya but I haven’t been able to find any other outdoor rated sockets. Sometimes the wifi is a little fiddle as the pool equipment is away from the house.
My pool heater is a big three phase heat pump and I was worried about how I could get a big enough relay to switch. In the end the heat pump has a flow switch that turns on and off with a smaller flow pump that could plug into a 10A GPO, I use the other socket for the 10A filter pump.
For the three phase heat pump I use a Shelly 3EM with CT clamps for power monitoring. The 2x 10A sockets report combined power via local tuya. So I can monitor the pumps and heat pump separately and control as two different loads in EMHASS. I set the run hours for the heat pump to the hours of extremely_low (< 5¢/ kWh) prices for the day. I set the filter pump to run for a certain daily energy or a function of the solar pv forecast for the day.

Matching your Air Conditioning to Excess Solar.
Again for those long days of negative feed in, matching your air conditioning to consume your excess solar is an excellent sink for all that very cheap energy. Your household stays cool, bonus if you work from home, have pets and it also saves having to blast the aircon in the afternoon when the prices are high.
There is a great project which uses the DRED interface on most aircon systems to limit power consumption using a set of four relays: Controlling Air conditioner using Demand Enabled Response Device per AS/NZS 4755
My premise was to change the setpoint to keep the aircon in the ball park of my excess solar consumption. If I’m drawing too much power, I raise the set point, and the aircon draws less power. if I’m generating too much excess solar I reduce the set point and the aircon draws more power.
To calculate the relevant set point automation I am using the following formula:
SetPoint = ExternalTemp - CoolingFactor/ExcessSolarPower
I was also playing around with InternalTemp as a variable, but that doesn’t seem to have much impact on the long term power consumption.
The CoolingFactor is in (W / °C) and is different for every household, depends on how big your AC is, how good is your insulation and thermal mass. For my household I find a cooling factor of 1500 W / °C works pretty well. I set up the CoolingFactor as an input_number helper.
I use a template calculate the helper to actual excess solar power available for HVAC.
Finally, I have an automation which is triggered when the excess solar power changes to change the setpoint of my air conditioner, in this automation you can see I also moderate the power by the battery state of charge, so my battery fills first and then in the afternoon once the battery is full, the aircon gets the bulk of the power to drive down the house temp.
Interested to hear how others are managing their aircon with HA and Amber low prices.
