Yet another which controller?

[Jim Danforth]

So here's my plan, and I'm open for input.
Just learning Arduino, but having pretty good success.
I have a greenhouse that I want to monitor by wifi, and log temperature from at least 2 nodes. Then later use that data to control some small heaters.
2nd monitor soil moisture, and control watering.

I've been looking at homegenie, but the arduino side seems to baffle me, but I haven't had load of time to devote until this week. Need something cheep/free on the controller side, and I'm building some arduino sensors now.

HomeAssistant - perfect one.
