Hayward Heat pump integration

[stepsolar]

Hi Alex, with these protocols would it be possible to also integrate the Hayward heat pump via Modbus?

Heat Pump Protocol 51

NeoPool driver already supports the heatpump: https://tasmota.github.io/docs/NeoPool/

I didn't understand how to make it work what you suggest. The heat pump has its own wifi module and app for control. In my opinion, you can retrieve the values I read with apps, such as temperature and more.

that's a missunderstanding

NeoPool HEATING is only the heating mode of Sugar Valley Pool systems, it does not communicate with any heat pump. NeoPool does not support heat pump protocols.

@stepsolar This integration does not communicate with any hardware directly, it uses the Tasmota with NeoPool module via MQTT. Tasmota with NeoPool module communicates with the hardware and provides get/set commands via MQTT. It supports a lot of Sugar Valley pool systems protocols but no heat pumps.

But could you put a tasmota module on the heat pump and communicate directly with it? Maybe I found the pump codes you could add to tasmota?

Yeah, this is theoretically possible, but do you really have any idea how much work this takes? Unfortunately I don't have the time for, sorry

@stepsolar You can buy a wireless module for your Hayward heat pump (a Hayward branded one or a "generic" one) and use the Aqua Temp app and Aqua Temp integration in HA. Here's a link with the generic WIFI module, same as the Hayward branded one but at a fraction of price: https://heatpumps4pools.com/product/thermotec-inverter-wifi-module/

Maybe you can just connect your heat pump with the AUX switch on the sugar valley to switch between on / standby

I put the heat pump on max. temperature and arrange pool temperature via the oxilife this way.
