Heya. During the day sometimes we get some insane spikes in the energy price. I wan't to lower the heat pump setpoint during those spikes.
I wan't to activate a switch (which lowers the set point on the heat pump) when the current price is above average for that day +10. So if the average for the day is 100, then I wan't to activate the switch if the current price is above 110.

The heat pump switch has idx 348.
The current price has idx 358.
The mean price has idx 361.

nvm

I think I got it working with this script.

Code: Select all

return
{
    on =
    {
        devices =
        {
            'Tibber - Current Price', 
        }
    },

    logging =
    {
        level = domoticz.LOG_DEBUG,
        marker = 'heatpump control',
    },

    execute = function(dz, domoticz, variables)
        local heatpump = dz.devices('heat pump switch') 
        local meanprice = dz.devices('Tibber - Mean Price')
        local currentprice = dz.devices('Tibber - Current Price')
        
        if (currentprice.sensorValue > meanprice.sensorValue + 10) then
            heatpump.switchOn().checkFirst()
        elseif (currentprice.sensorValue < meanprice.sensorValue + 10) then
            heatpump.switchOff().checkFirst()
        end
end
}
