MY18B20 sensor #562

Hello. In the source code of the firmware I found a mention of the MY18B20 sensor. I think this is a great idea! It would be very convenient to connect this sensor to the TS0201 TZ3000 sensor, since it is powered by two AAA elements.

Is it possible to get firmware for TS0201 TZ3000 with MY18B20 support?

The interface in TelinkMiFlasher.html is not yet ready to work with different types of sensors.

Thermometers can service a maximum of 2 MY18B20 sensors. But to reduce consumption, each MY18B20 is connected to different outputs - the poll is carried out in parallel.

Today there is only a firmware build for the TB-03F module TB03F_v48.bin

Added beta version:

  1. One MY18B20 on PD2 TS0201S1, ZTH01S1
  2. Two MY18B20 on PD2 and PD4 TS0201S2, ZTH01S2

Temperature from MY18B20 is transmitted in BTHome format.
