My entirely 1-wire station recently suffered from a nearby lightning strike and my USB 1-wire adapter died and also my indoor temp DS18B20. Everything outside survived. I had a spare USB adapter so was soon up again then finding my indoor temp reading was missing.
I replaced the DS18B20 sensor and got it populated properly in Dallas 1-wire.exe.
All working except the reading is nuts 2.8 deg C indoors when it is actually over 20 deg C. If I touch the DS18B20 the temp rises.
I then replaced the DS18B20 with another new one but it still reads 2.8 deg.
Does anyone have any idea why this could be?
thanks
Ian
