problem with Dallas temperature
-
hello,
I have problems with my 1-wire node, so I used two buses (pin2 and pin3).
all my temperatures are visible but some have the same id./** * The MySensors Arduino library handles the wireless radio link and protocol * between your home built sensors/actuators and HA controller of choice. * The sensors forms a self healing radio network with optional repeaters.

for me the first 2 lines and the last two are different probes but with the same id.
how can I have a single id ?
thanks

If you have two nodes with the same ID, the MySensors system can not work good. You solve this by clearing the EEPROM, see https://www.mysensors.org/build/debug at least for one of the nodes. After this, the gateway will send a new node id to the node.

hello,
I just deleted the eeprom but I still have the problem.
