Share My Creation Heatpump controller

Here is a screenshot of the heatpump controller I have built and use to heat and cool my house.
This is just the phone app that allows me to control and monitor multiple heatpumps remotely.

The whole system is built around an esp8266 and has predictive heating/cooling from openweathermap.org.

The heatpump is air-to-water and feeds heating/cooling into my underfloor heating system.
It is built from a recycled conventional (not inverter) air-to-air air conditioning system.
I use the external unit without its controller and have my own controller running the system.

How does it connect to the ESP8266 controller?

It uses MQTT to connect.
Previously I controlled the heatpump via the remote thermostat but I decided to move the control back to the heatpump itself. The problem I had previously using Telegram is that it only works using SSL and this uses too much memory on the esp8266. Moving to MQTT has solved this memory problem so I could move the communications back to the heatpump.
