Hi guys, my house currently has a thermostat which is really old and I am trying to upgrade it to the smart thermostat so I can control wirelessly.

However, my heating system is very old and most of the smart thermostat on the market were incompatible. When I was looking around to find one, I found this: https://www.kickstarter dot com/projects/wifiswitch/wifiswitch-advanced-energy-saving-thermostat-devic?ref=user_menu

It says it's called Wifi-Switch. Apparently this seems very good for me but just wondering your thoughts?
Or do you guys have any suggestion if there's any smart thermostat I can buy to replace my old thermostat? My wall only has 2 relay switch wires for the heating system. Thanks!

The very oldest thermostats use the same technology as the newest (i.e., 24VAC) unless you have electric heat which uses 110/120VAC or 220/240VAC.

However, a programmable thermostat (from the oldest to the newest) requires power which a 2-wire system doesn't have. But, it's easy enough to add an external power supply. The images on the web site you provided a link to show another external wire/cable going the their their thermostat.

You can do that with any smart thermostat!
