question

Hi,

we have a Sprinter Van with Touch 50 in the coach, Cerbo GX, and awning, poptop, rear doors, etc.

We would like to see the state of some door sensors when in the driver seat, to avoid driving away with open pop top, extended awning, etc (which we can't see from the driver seat).

Is there a way to do this via the all-Victron system our van already has?

1. What door sensors would you use that play well with the Cerbo?
2. What is the best way to realize a secondary dashboard screen* without making it a big engineering/coding project?

Any other ideas or pointers welcome, including to outside the Victron ecosystem. But a Victron solution seems the most desirable of course.

Thanks for reading,

* I've read here that a secondary Touch 50 causes problems. I hypothesize it might be the confusion from the CEC channel on HDMI that sense the touch inputs. Since I wouldn't need to operate on of the Touch 50s, could a HDMI splitter work, that splits out the CEC channel from the secondary screen? e.g. like this one: https://www.amazon.com/dp/B09B7B7BM8/?coliid=IBA147ZDPAFOH&colid=W5RNPTK3F5R&psc=1&ref_=lv_ov_lig_dp_it
