Hi. Would it be possible to implement a Aqua Temp controller? It’s widely used for controlling heat pumps (pools)
From the App Store description:
"Auqa Temp makes it possible for you to communicate with your heat pump pool heater easily from a local WiFi network(IEEE 802.11b/g standard WiFi network), or remotely over the Internet. Auqa Temp is compatible with heat pump pool heaters that must be with WiFi module that provided by the product suppliers.
With Auqa Temp you can:
be able to monitor the state of the heat pump pool heater, such as the available hot water volume, the current outlet water temperature, the current running mode, etc.
be able to set the state of the heat pump pool heater, such as ON/OFF setting, target water temperature setting, mode setting, timer setting, etc.
be informed of any failures of the heat pump pool heater.
be provided with considerate service that the suppliers will solve any detected problems of the units in the background before you ask for assistance."
The Aqua temp app uses a HF-LPT230 Low Power WiFi Module
