hass is None

After every fetch of data from TTN, there is this error in the log:

2024-03-04 07:56:04.126 ERROR (MainThread) [custom_components.thethingsnetwork] Unexpected error fetching The Things Network data: Attribute hass is None for <entity unknown.unknown=unknown>

The sensor data is there, it is not missing.

I am not getting this error but I get

WARNING (MainThread) [homeassistant.helpers.entity] Entity sensor.soil_v2_26_raw (<class 'custom_components.thethingsnetwork.TTN_client.TtnDataSensor'>) is using self.async_update_ha_state(), without enabling force_update. Instead it should use self.async_write_ha_state(), please create a bug report at https://github.com/angelnu/home_assistant_thethingsnetwork/issues

This was reported with #17

I will look at fixing this one and see if that helps with your case as well.

I just found that I have this error only with 2 devices from 7. Maybe it is because I renamed a device or a sensor?

[martin3000]

I changed the code in TTN_client.py and this seems to fix it:

    async def async_set_state(self, value):
        if self.hass:   # jms
            self._state = value
            await self.async_update_ha_state()

Thanks @martin3000 - I added the deprecation fix and your check at https://github.com/angelnu/home_assistant_thethingsnetwork/commit/ccf6fb6e1086817d5c00ca86d1bc06839e056c7a

Please let me know if that fixes the issue
