State of the sensor network

1. Sensor 202 ( entrance ) - network off line. I think the machine its self is OK. Contact networking again.
2. Sensor 201 ( central stair case ) - one line and working but I think pressure pad is down replace.
3. Sensor 203 (far staircase) -network ok. won't work from external power supply, Need to check pads. Fix put in 10K resistor to RX ping to ground. - Might get USB power supply to.

I think I can get 2 up and running by end of week. Possibly 3.
