Hi,

Trying to implement this and only seem to have it partially working.
Made mention of it here,
https://community.home-assistant.io/t/afterbuner-mqtt-to-homeassistant/279936/17

Not sure I completely understand the Climate section.
It's a bit outside my BASIC programming familiarity.

Any Suggestions?

Thanks
