Comparitive pricing - vs existing.

From Streakwave:
Mport $79
Ceiling PIR $42
Install cables etc $5
Install time $20
Total: $146 .... and a lot of cables on the walls, ceilings and a power socket used up.
Self contained wirless PIR, battery powered, http://www.screwfix.com/p/lightwaverf-wall-mounted-wireless-pir-white/77828 $30 RETAIL (ex sales tax)
For widescale adoption, in non industrial situations, I still think we need really low cost wireless (not necessarily wifi) battery sensors

This device requires some kind of master controller, right?

Re: Comparitive pricing - vs existing.

Well I agree that the sensors should be wireless. I mean the motion sensors and temperature sensors look plenty big enough to have wireless built in to them. Of couse that would increase the cost some but I think it would be worth it if it only increased the cost of each sensor by $10-$20.

Agree'd i thought when i saw them the mFi sensors were wifi as well if they aren't thats depressing greatly.

They do, essentially some kind of alarm panel - which costs from around $60. No, it isnt web enabled or Ethernet (without some home hacking) but it shows that a battery wireless sensor can meet that price point - saving twice over in equipment cost and install effort.

Re: Comparitive pricing - vs existing.

Here's another product for example...
www.gokeyless.com/product/1722/5/zwave-ezmotion-sensor
$80 motion sensor that communicates via Z-Wave, detects light, motion, temperature and reports back - a MiCasaVerde for $200 can receive these, unlock your doors, talk to your security system, etc - and not a single wire on the wall or device plugged into an outlet.

Give it a few months of 'live' equipment. I bet you someone will come out with hi-cap battery packs for these units with WiFi built in. Then it will be fully wireless.

You cant do wifi by battery - the protocols spend too long handshaking and exchanging rubbish all the time that they would sink the battery too quick.

Wireless sensors work by sleeping 99% of the time, then coming on for a fraction of a second, then sleep again.

What might be possible as a fudge is to build a receiver for existing low power PIRs and contact closures connected onto either the RJ45 / serial / contact inputs on the mPort and simply use that as a bridge. We do this already using the serial ports on Bullets (and various other routers) to talk to little microcontroller based sensor boards. ie

battery powered sensor + 434Mhz transmitter ----> 434 receiver+ microcontroller with serial ----> bullet serial port -----> 5.8G to data centre miles away
