Warning
If you want to use this script, please DO NOT UPGRADE to the latest Gree Firmware 1.44 which is breaking the usage of it. You have to be or to keep at least the version 1.31 to be working.
If you own a Gree heat pump integrated locally in Home Assistant, you probably know the problem:

(especially painful with Scheduler Card or automations)
