The AstroHub and JoloFocuser open source projects - support for both temperature and humidity.
The usage of the first two types should be configured in Temperature & Sky settings tab. The other two option are automatically detected and used on focuser connection.
See the section External Sensors for more information on how to use the temperature and humidity readings.
The sensors are used or can be used by the following APT features:
Temper/TemperHum notes: PCSensor are an unreliable producer, their communication protocol is changing with every production batch and they provide zero documentation and cooperation. To make the things harder, it is impossible to identify the batches via code and some batches look same physically...
If APT can't display the temperature or humidity readings correctly follow these steps.
1. Go to the APT folder,
2. Rename Temper.DLL to TemperX.dll
3. In the APT folder you will find OldTemperDLLs folder.
4. Start from newer to older DLLs to copy them in the APT folder.
5. Rename the copied DLL to Temper.DLL
6. Start APT
Repeat the procedure till you find the DLL which works with your sensor.
This is one time operation because next APT installers will keep the DLL you have applied.
