RF based thermostats

Hi All!

You all know about RF based thermostat solutions to make home-heating efficient and cost-effective.
The problem is that I hate the thought of wireless communication for this purpose if it has any negative effect.

Ok, I know that constant communication with the thermostat would be dangerous (868MHz for RF), but do these gadgets have constant communication at all? When do they send signals, what happens in the idle state? Do they send signals even when I am sleeping or only when it needs to notify the base station about a on/off state?

Also, is it bad to be near the base station?

Thanks,
Daniel

p.s.: WIFI based thermostat is not an option, because I have no WIFI because of radiation, so RF is the only question here.

My guess with these RF based thermostats is that they may not all be alike, so it would be best to read the white papers on each device to tell how they operate.

A transmitter was put on my gas meter which was constantly pulsing RF as determined with an RF analyzer. The gas company however told me that it went back to sleep after being prodded once a month for a read. However, I obtained the white papers on the meter and it could be set in a sleep mode which would only transmit briefly when prodded or in a permanent bubble-up broadcast mode where it pulsed continuously.

I bought a fireplace heater, that was supposed to be NO electric non tech. It turned out to be a smart stove and RF signals transmit all the time w/ the remote therm. Fortunately I did not have it installed yet and attempted to return it w/ no luck. It is in litigation now, as I would not want to live w/ any such thing. It would bother me as all those things that transmit do and even if it didn't I do not want the other health issues that would be the outcome.

The plaza hotel installed those. Not so popular to stay there with many anymore. Who wants that in the room along w/ wifi.?

My new trailer heater will operate by wired therm. powered off the gas [propane]. Currently my heat has the same thing where I am now. No problems! The only way to go.

Thanks guys!

Ok, so I found this for instance:
http://cdn.shopify.com/s/files/1/0686/7173/files/Q3RF.pdf

It says:
To increase the lifetime of the batteries, the thermostat will not
transmit signals continuously. Instead it will repeatedly transmit
the actual signal every 5 minutes. Therefore, the regulation of the
heating or cooling will continue even after a blackout.
(funny that the translation in my own language only says it only transmits signals when switching occurs, no mention about 5 minutes)

Questions:
1. Is this 5 minute signal dangerous if the transmitter is close to me when I am in bed? Should I opt for another solution?
2. Also, should I be afraid of the base unit that accepts the signals or is that completely harmless?

I was even thinking of a way to take away energy from the transmitter (for instance: taking out the battery always), but that is probably not really doable in a normal way.

Thanks,
Daniel

Re: RF based thermostats

Please please please opt for another solution!!!!! I know it's a pain to look at the little hole in the wall the wired thermostat made, but really I love them. Where I am now they tacked the wire down along the door frame and along the floor to the heater. My trailer has the hole. I am going to cover that w/ furniture right?

All I know is it's going to be safe and that makes me happy.

Re: RF based thermostats

Thanks JDark, I will get the wired one then. Great help, thank you very much!
