For single-phase domestic electricity meters (e.g. Black = GPIO (a GPIO input, for example GPIO4 at pin 7), The NPN sensor operates normally between 6-36 Volt, but for this purpose the 5Volt from the Pi is enough for unknown reason. I want to get rid of the RFXmeter with infrared sensor, so this is a good opportunity for switching hardware. For example a meter may output 1 pulse for every 10 litres of water. All set, the sensor is placed, and its time to expose the measurement values and send them over to Home Assistant. In case you want to store the Python script somwhere online, you can use the following command on the Pi to grab the file: To test the changes, give the Pi a reboot with command: If everything is set correct, the following line will be visible in the console after reboot: When you now hold a piece of metal within the 4mm sensor range, the led will activate, and in the console screen the following lines should be visible: The Response:ok is a confirmation that the JSON call to Homeseer is done correctly. Pulse frequency (Hz) / 7.5 = flow rate in L/min. Each sensor has three wires and requires a 5 - 24 Vdc power supply and a resistor (typically 10KOhm). (Only 2 and 3 generates interrupt! You can also set the frequency that the sensor will report the water consumption by updating the SEND_FREQUENCY. The ESPhome configuration has been updated to support this feature. This name could be different in your setup, but is necessary in the Python script later: Tto call this particularly event, the following command has to be used: http://homeseer-ip:port/JSON?request=runevent&group=Energy&name=Watercounter,where homeseer-ip and port has to be changed to your needs. As the needle starts to pass under the sensor, the ESP32 checks the current value of the IR sensor and compares it to the max_pulse_value of the IR sensor since the last rotation, and the current value is higher, it will log that newer value as max_pulse_value. Wiring this sensor is a really easy job. datetime.datetime.now().strftime(%a, %d %B %Y %H:%M:%S) the Elster A100c) each pulse usually equals one Wh (1000 pulses per kWh). Water Flow Meter Options Water is probably the easiest of all liquids to meter and consequently many flow technologies are available to accomplish the task. / Terms & Conditions It is available in sizes DN 40 to DN 400. I expect earlier that the sensor should not operate as it should because of the voltage difference, but in both cases, its working fine. Adjust the trimpot so it just triggered when the disk is underneath. * The sensors forms a self healing radio network with optional repeaters. You can find step-by-step guidance in the Flash ESP chip with ESPHome node firmware article. The cable has 2 wires for single pulse switches and 3 wires for double pulse.
