advice needed

[vooteleaer]

Hello, I'm new here, and havent touched homegenie before.
Basically, I want to automate some things at my summer house - I have converted car gasoline heater to propane, right now I use digital thermostat and some relays to control it, but would like in future to have nice 7-inch LCD touch screen with homegenie controlling it.
It's quite primitive, like early eberspächer heaters - DC motor for fan, solenoid valve for propane, ignition, thermal switch, all operating at 12V. So, 3 outputs and 1 input for heater, plus room temperature sensor.

So, is this doable and how?

concerning the screen:
I would advice to get a 7 inch tablet and use the web interface, it's pretty touch friendly.

personal advice: get a windows tablet they're dirt cheap below 9 inches and I'm working on a windows store app for homegenie. (not sure yet if it'll be win8 of win10 since win10 will be released this summer and it'll be a free upgrade for all devices)

The screen is not the problem, but switching 5A loads.
I have 10" tablet, maybe I'm gonna use it for remote control.

The heater works like this.
At start, thermostat measures room temperature.
If its less than set value,
1 fan turns on
2 gas solenoid turns on
3 ignition turns on (spark every secon)
We have flame in combustion chamber
4 thermal switch opens, spark turns off
Run until set temperature reached
5 gas solenoid turns off
Run until thermal switch closes
6 fan turns off

Right now its done with digital thermostat and two 2-pair relays.
