My threaded onewire temperature sensor broke recently, after unscrewing/screwing the wire from it for a couple of years. Please see attached picture below. After I plugged in another one, it cannot read out the temperature on any of the five inputs, and I have tried with a couple of different temperature sensors. I am afraid that when the first temperature sensor broke it might have short-circuited and damaged something inside the brewpi 3. I have measured, inside the brewpi, the supply voltage it puts on the pin to the sensor, and it reads 5V, so that is fine, but I am afraid something happen to the data input.
Is there a way to troubleshoot this?
Sorry, didn’t make myself clear. Since I’m using the unit for mashing, I’m only using one sensor at a time. But I tried with 3 different, one at a time, and no reading.
In that case it is likely that the onewire master chip is damaged.
If you cannot discover any sensor, plugged in one at a time, then the only fix is removing and resoldering the bus master.
Which of the parts is the bus master on the PCB? Can I buy the spare part from you, or is it a standard component I can get from an online electronic store?
