Default Idea for motorhome gadget?

This is more for the techie types I think.

I am thinking about getting one of these 4" tablets and permanently mounting it in my van. I will get also get Raspberry Pi and link them via wifi. Due to the built in IO ports I can them control anything in the van via the android tablet. Just after christmas I will have my motorhomewifi.com 3g/wifi router set up so the van will be comprehensively networked

I will configure the tablet to give me local weather wherever I am, temperatures from 2 digital thermometers one inside one outside.
I will be able to control the lights.
I will setup news feeds, email notifications and server monitoring.
I could also link in external cameras for additional security when wilding.

So many more ideas as well.

£49 for the tablet
£35 for the Pi
Probably no more than £20 for the electronics. So around the £100 mark.

That could be useful and it certainly qualifies as a Funster gadget. Motorhomers can spend an hour a day staring at their BM1's, you could while away a whole wet weekend with that

Be interesting to see what uses you can put it to

I find doors are good to find out temp inside and outside

Just kidding - keep us informed on what you get up to. Interested in what you can do with the Pi

Good idea Jim, might look into adding a battery monitor to it then I could get rid of the NASA.

However you look at it, isn't it just a watered down version of what we all have in our homes.

if you don't already have one...

how about a thermostat/timer for the water and heating

or even a frost control mechanism where if the temp drops the PI kicks the heating in or even remotely via a mail/text - on the rare occasions you may not be in the van overnight!!

No idea what you mean Buttons sorry. I never had a touch screen when I had a house and nothing was remote controlled via a portable panel not even my puter or tv.

Timer might be hard to integrate into the truma system, would have to look at the control board. If it is just a simple switch and variable resistor then it should be doable.

A frost alarm would be possible to send an email but that would mean you would need to be on hookup if you don't have solar panels. The pi doesn't draw a lot of power but over a long winter it may have an impact on batteries? Not sure would have to check on that one. It wouldn't be high on my priority list as I am a full timer and the heating is on all the time anyway

I have found the 5V power supply for them both though. Just need to find the USB pin outs for the power supplies.
