NodeMCU + 1-Wire

Hi, Discovered brucontrol a few days ago and after plenty reading i ordered a license, mega 2560 and some other stuff to get it up and running.

Thought while im waiting for delivery of parts i would reflash an old brewpiless controller (NodeMCU board/ 2x DS18B20/ 2x 5v relay) with the firmware to try out the software.

i removed the relays from the circuit so i could get the sensors setup first.

Flashing went fine,brucontrol connects to the interface fine but after adding the 1 wire devices to the workspace with index 0 and 1, no temperature values are shown on either

I think the wiring is correct, the only difference from brewpiless wiring as far as i can tell is the data line connects to D5 not D6

looking at the interface communications window i get Rx -?#?# and Tx - ?200?201 repeated every second.

Any idea where im going wrong here?

I believe GPIO 5 is pin D1 on the NodeMCU. Please re-wire and restart the NodeMCU to read the sensors. Alternative to power cycling, you can send a %3 in the Interface Communications (Advanced button) message transmit section to re-initialize the 1-wire sensors.

Please try these and report back!
