Custom sensor: changing state API vs Service API

hhaim · April 2, 2019, 7:03am

I’ve implemented a custom component and I needed to change the state from automation.
It is possible to change the state using the API (set_state) and debug console but this state is changed when the API self.async_schedule_update_ha_state() is called (it seems somthing else is changed and when this API is called the old internal state is updated back to the GUI)

So I’ve implemented a service API for that and it works (the code to update the state using service is here)

    return;

if d['cod'] != 200:
    _LOGGER.error(" Invalid response from OWM {} ".format(d))
    return

if self._debug and self._type == TYPE_RAIN:
    _LOGGER.error(" wbi_raw_data {} ".format(d))

# estimate rain
rain_mm = 0
if "rain" in d:
    # accurate 
    if "1h" in d["rain"]:
        rain_mm = float(d["rain"]["1h"])
    if "3h" in d["rain"]:
        rain_mm = float(d["rain"]["3h"])/3.0
else:
    # this is estimation base on string 
    if "weather" in d:
        w = d['weather']

My questions:

Is it possible to have a way to change the internal state without service API?
In which case the set_state is used is it change only UI state

thanks
