wireless piezo light switches.....

I have a job waiting for one. The problem is that distance between the switches and the distance between the receivers is limited.

I have been trying to get info from a mfgr. for my particular application. No luck. Even Leviton won't give me an answer.

I am supposed buy the unit, install it and then if it doesn't work, tear it out and send it back. And, I guess, eat all the labor and trip charges, plus fix any damage to the wall the sticky tape may have made.

So, I am still waiting. It's been about three years......but I'm not doing R&D on my dime for any manufacturer.

i've got a bit more of a time constraint than that... smart home in irvine has an outlet store....
a smarthome branded piezo switch and relay is about $90... i'll let ya know how it works...

Hello Fulthrotl,
I was trying to understand what you meant by a wireless piezo light switch?
What part number are you looking at when you referenced Smarthome?

Is it the IR motion sensor with Piezo output alarm?

piezo switches are self generating, and don't need batteries or charging.

went by smarthome in irvine today and picked up these:

leviton WSS0S-POW switch
WSP05-080 relay

$193 for the pair. about twice what the smart home branded stuff goes for.

Please, let me know how they work and what kind of range you are getting. Also, if the switch can be on one floor and the reciever on another.

I have some experience with weak signal radio. It doesn't take much to attenuate a weak signal to an un useable level.
 
I have used the EnOcean switches (not piezo; they generate the voltage electomagnetically). I get about 70-90 feet in the clear, and haven't seen much attenuation thru a regular sheetrock-and-metal-stud wall.

Thanks for the part number Fulthrotl,
Interesting concept.

I have a good number of RF home automation devices in my home that operate at 915Mz (Insteon) ( both battery and line powered). The advertized range is 150ft open air.
In practice, as k8Mhz mentioned, the signal is fairly easily attenuated in a home or buisiness. Not uncommon to fail after about 50 -70ft in doors. I once tested a emitter/receiver pair in open air and got over 100ft easily. That same pair inside the home failed at 60 ft.

Since the device you pointed to advertized 50 -150 ft you may experience a fairly short operational range in some cases.
These devices being 315 Mhz might help or hurt I am unclear which. In theory maybe better?
At 915Mhz I find that something as simple as a person walking by can upset the reliability, I suspect multi-path interference?

Good luck, it will be interesting to hear what you think.
