Prevost Coach iPad Connectivity Issues -- 2

I require a skilled technician proficient in iPad device troubleshooting and Prevost motor coach systems. The remote iPad in my coach is experiencing connectivity issues which means I can't control my lights or generator. Oddly, the shades and AC are functioning correctly so there seems to be a specific issue with these features.

Key task involves:

- Diagnosing connection issue between the motor coach systems and the iPad
- Not sure about other devices, the functionality needs to be checked with those too.
- This issue specifically involves control of lights and the generator. Any solution presented needs to his into account.

Appropriate expertise in iOS devices, general troubleshooting, and familiarity with motor coach systems would be beneficial.
