The code works but you can not switch from cool to heat or heat to cool. E.g. if you live in an area when the overnight temp. difference is large so you need cool in day time and heat at night, the code won't work.
You need add payload["SystemSwitch"] = 3 for cool and payload["SystemSwitch"] = 1 for heat as below:

if (action == "cool"):
payload["CoolSetpoint"] = value
payload["StatusCool"] = 1
payload["StatusHeat"] = 1
payload["CoolNextPeriod"] = stop_time
payload["SystemSwitch"] = 3

if (action == "heat"):
  payload["HeatSetpoint"] = value
  payload["StatusCool"] = 1
  payload["StatusHeat"] = 1
  payload["HeatNextPeriod"] = stop_time
  payload["SystemSwitch"] = 1
