Hi,
I have bought recently a Lan Controller board.
It's a great platform with a support of interesting protocols. 8-) 8-)
I have a couple of consideration about possible future features:
1- support of DHT sensors family.
On the Arduino world there is the DHT library that allow to support DHT sensors (e.g. http://www.seeedstudio.com/wiki/Grove_-_...Sensor_Pro).
These are sensors (DHT 22 is a calibrated sensor) that allow to monitor Temperature and Humidity and in home-automation project or server farm monitor project are very useful. They are for sure more expensive that DS 1 wire Dallas sensors but they can measure humidity (take in mind that DHT11 can be found at 3$ on web).
NTC sensors has a lower accuracy.
What about a possible support on LanController ?
2- SNMP vs webservices
LAN Controller support SNMP. This is a great thing in project where there is an SNMP trap receiver (e.g. server farm, data center or enterprise enviroment).
In home automation project it is more useful the support of web services interface or something that let the LanController publish the status of its sensors on a server and receive in the reply a command (switch on the relay).
SNMP is transported by UDP while web services are transported on TCP. It's quite difficult to open an UDP port towards internet to allow a WWW UDP server to send reply to LAN Controller. With a TCP transaction it should be simple.
What do you think ?
On the arduino world there is the support of Pachube and Nimbits that are quite interesting.
