I agree Don B. about the lack of board traffic...

Here is some thing to discuss. About a month ago we had a t-storm and took a near lighting strike (200 ft) which knock out 20 of my 24 temperature sensors. I did not realize this for a few days since we were between the heating/cooling season.

At first I thought I had a short but after breaking the 1-wire bus into segments to troubleshoot, I realize these sensors were fried. The four remaining sensor were the inside/outside air temp and the upper/lower DHW tank (plastic Marathon).

The following is the layout of the 1-wire network...

[WEL]----[T-StatMonitor]----+-+--[GSHP-Sensors]
| | | |
| +---[InsideAirSensor] | +--[DHW/DSH-Sensors]
| |
+-----[OutsideAirSensor] +----[GroundLoopSensors]

Yesterday I start with the repairs since we our just starting to enter the cooling season. I had bought a 1-wire (RJ-11) USB adapter and tested each of the fried sensor using the Dallas 1-wire Viewer.
Next I insert ten new Dallas DS18B20-PAR temperature sensor into a breadboard and used 1-Wire Viewer to record the device addresses as they were inserted.

Today I updated my WEL configuration with the new addresses and connected the breadboard to the WEL 1-wire network.

This week I will be soldering the leads to the thermistors and install them on the heat pump.

Any one else lost temp sensor to lighting?
