[maemo-developers] N800 as a home automation/monitoring remote

[From: John Holmblad]

David,

regarding HA protocols, the one protocol that I know of that IS wireless 
is the Zigbee protocol stack based on IEEE 802.15.


I know of one company, Colorado VNet, that has put  Zigbee + a wireless 
mesh router (basic I am sure) into each light switch in its wireless 
lighting control system. Here is the url to the www page for that 
product line:

    http://www.coloradovnet.com/wireless/wireless_system.aspx

I have yet to learn how the mesh network gets its initial control 
profile. The sales person who initially tried to get an explanation for 
me left the company. I surmise that it is necessary to purchase at least 
one of their wired<=>wireless gateways in order to perform the initial 
config.

Colorado VNet have also experimented with using the N800 as a control 
device although to my knowledge they have not released a product 
offering that uses the N800.


Best Regards,
