Heat Meters
See Micronics Heat Meters for information on how to connect Micronics Heat Meters.
The first Micronics heat meter provided data immediately as expected, matching values on the screen. This can be viewed in the Node-RED software in the debug window, where one can inspect the data telegrams being sent and received. [1, 3 ...] represents device 1, function code 3 (read register). The response should also start with [1, 3 ...]
However, the second meter provided incorrectly formed responses and will require further investigation. It is the same setup entirely, so the only difference could be the polarity is reversed on the RS485 line.
