Hacks for the next generation Fluksometer, version 3E (FLM03E) - find following sections providing diverse documentation on experience gained.
For the FLM03's MQTT features, refer to MQTT.md; for a tiny server to chart FLM03 readings, go to MQTTrealtime.
Also the FLM03 can be tweaked to get an on-board visualization capability; for this, please refer to the corresponding flmlocal flm03 branch
To interface one pulse meter with two pulse inputs, use a little "pulse doubler", described in interfacing.md
