Automation /Electrical engineer

I am in the process of designing 18ft expedition trailer. We will be using Loxone products (mini server) and domotics open-source interface as HMI software. We will be also using EnOcean wireless lighting switches and many of f level sensors, small water valves (actuators), water pumps, etc.… there will be an override panel in case of the trailer network is down or automation down; we will able to operate everything with an override switch. There will be Victron batteries, an Inverter, a chargers battery management system, and a solar panel. An experienced instrumentation and automation engineer with electrical knowledge can handle it. The preferably who know loxone products and domotics but if you never works with these products. It shouldn’t be the problem. You can study and get help from the vendors. What will be looking is that; Single line diagram Inst index Lighting and power outlets drawings Override switch panel design Battery system design Creating control logic and HMI Trailer Network diagram And other things that I may forget
