We have two RTD probes in coolers, one with the original probe, one with a proper industrial replacement probe. Both seems to send 0 degree C readings intermittently. the sensor is transmitting. From what I could find is that this means the connection between the probe and the transmitter is lost? What explanation is there for this, we have seen this on three transmitters already.
while reading the RTD value device is encountering overvoltage/undervoltage error. @jacob@TravisE_NCD_Technica can we add a condition in the node red so that when the reserve byte is non zero it just outputs the error code and not the complete msg.
It does not seems to happen with other probes. in fact when I moved that sensor to measure room temperature, it didn’t occur again. But it does occur with multiple RTD sensors we placed in coolers.
The only other thing that these sensors had in common is being externally powered. Is your denk model just battery powwred? Not sure if this could cause interference
These are placed though to retransmit signals from sensors further back from the main gateway. Eventually they would have to be powered. I may be able to set something up temporarily to test. Are you able to run yours on power to see if you notice any changes? We’ve determined that it wasn’t the temperature affecting the readings so it could be inside.
