Hi everybody!

I need to control my home heating system with my raspberry pi.

I have a temperature sensor working and a tellstick...

Does anyone knows of a simple (and cheap :P :D) relays working using wifi or tellstick?

Depends on where you live - but almost any "breaker" operating at 433 MHz would do the trick I guess. Try "Conrad" perhaps they exist in your country... You should be able to find something for less than 10 EURO that workd with the tellstick.

Good luck!

I am sorry if I give a little bump to this thread but I'd love to receive a little help...

My heater is an Ariston AS24 and opening it I've found what we call a "clean" contact.

I mean that if I simply interrupt a small copper wire the heater stops working.

I'd simply like to turn (safely) the heater on and off using my telldus stick...

I thought an LCMR-1000 (nexa) won't do the job because I think the LCMR-1000 would pass the 220 to the contact, right?

I'd really appreciate a little help from experts :)

Excuse me if I'm saying stupid or obvious things but I am just beginning to use electronics...

Thank you for your kind help...

Hi
Yes you can use the Intertechno ITL-1000.
It's a radio device (433,92 MHz). It is potential-free switching.
