Daly2MQTT also supports the connection of DS18B20 temperature sensors.

Definition of the sensors

The sensors are sorted by Wemos in ascending order according to their internal serial number. To ensure that the displayed sensor number one can also be assigned to cell number one, for example, proceed as follows:

• Connect all planned sensors
• warm up the sensors one by one by hand and see which value rises, e.g. in MQTT or /livejson.
• For example, if it is the value of the DS18B20_4, then mark this with a 4.
• Do exactly the same with the next sensor
• Once you have identified all the sensors in this way, you know the correct sequence

If at some time one or more sensors are replaced with new ones, this process must be repeated completely.
