It's over 18 months since I started the thread, and I refuse to go another winter without being able to remote control my central heating.
I want something simple to install and operate, no fancy wiring, must be controllable by GSM, not internet, and have no exorbitant ongoing running costs. I have a heating system with its own fairly sophisticated programming facilities to control zones and temperatures, which I can preset. So all I need is something to switch on the main switch. Must be cheaper than "Climote" (€300 + €40/year)
Here's what I'm thinking:
Anyone have any thoughts?

Here's what I'm thinking:
- A Tesco PAYG SIM card, stick on a few quid credit which never expires. (Anyone have any other info/confirmation about whether Tesco call credit expires, or SIM gets deactiviated after prolonged inactivity?)
- GSM Timer/Switch, STG£85 from http://www.amazon.co.uk/GSM-TIMER-SWITCH-CONTROLLER-POWERED/dp/B00B9ARK12/ref=sr_1_10?ie=UTF8&qid=1409791242&sr=8-10&keywords=gsm+controller (Amazon), or STG£95 from the with 2yr warranty.
- Looks straightforward from the manual. I'm not well up on electrics but I presume an electrician will be able to figure out the wiring diagram on the last page of the manual and connect inline with the fused spur to my heating system. I've contacted an electrician to see if he'll do the job.
Anyone have any thoughts?
