Panel Groups dialog is confusing about which entity should be selected for group_1_sensor

[gpbicego]

Describe the issue

In Solar Forecast ML 44.2.2, the Reconfigure Panel Groups dialog is confusing about which entity should be selected for group_1_sensor.

The dialog shows:

Format: Power(Wp)/Azimuth(°)/Tilt(°)/Daily-kWh-Sensor

and later says:

Daily-kWh-Sensor: Home Assistant entity_id of a daily energy sensor for this group.
The sensor should reset at midnight. The sensor part is optional in the input format, but strongly recommended for correct per-group learning.

However, the actual group_1_sensor selector appears to be intended for the panel group's live power sensor, e.g. an entity with:

• device_class: power
• unit such as W

rather than a daily-reset energy sensor in kWh.

For example, my correct configuration is:

• Panel group size: 5998 Wp
• Azimuth: 180°
• Tilt: 30°
• group_1_sensor: sensor.solar_power_production

where sensor.solar_power_production is an instantaneous PV power sensor in watts.

Why this is confusing

The UI currently makes it look as though group_1_sensor should be a daily energy entity such as:

sensor.solar_energy_daily → kWh

rather than:

sensor.solar_power_production → W

This can easily lead to a wrong configuration, especially because the entity selector does not make the expected sensor type obvious.

Expected behavior

The dialog should clearly state that group_1_sensor expects an instantaneous power sensor, for example:

Panel Group Power Sensor
Home Assistant power sensor representing the current output of this panel group.
Expected device class: power
Typical unit: W

The format description could then be changed from:

Power(Wp)/Azimuth(°)/Tilt(°)/Daily-kWh-Sensor

to something like:

Power(Wp)/Azimuth(°)/Tilt(°)/Power-Sensor

Example:

5998/180/30/sensor.solar_power_production

It would also be helpful if the entity selector were filtered to:

device_class: power

so energy, humidity, temperature, etc. sensors cannot accidentally be selected.

Additional suggestion

The same type of device_class filtering would be useful for the optional weather sensors too, for example:

• Temperature → temperature
• Humidity → humidity
• Pressure → atmospheric_pressure
• Illuminance → illuminance
• Power → power

I previously managed to configure my humidity sensor as the pressure sensor because the selector did not restrict the available entities.
