(Only 2 and 3 generates interrupt! * Created by Henrik Ekblad <, // The digital input you attached your sensor. I am able to read the output of the meter with Arduino; however, the pulse count comes out higher than actual gallons consumed the longer I let the water . Hi Rutger, Great, simple design. Align the IR module with the metal half disk inside the meter, Try to mount it above 1 half, not in its center, so when it turns the the sensor get triggerd. GPIO.cleanup() # Clean up. Type Volumetric Rotary Piston Roller Index Register (m) Size & Connections 15mm to 40mm BSPT Male Unions Duty Cold Potable Water up to 30C AMR Output (optional) T110 Reed Pulse Probe JTA4600 Reed Pulse Probe c/w Splitter Compliance & Approvals This mode requires constant power so you will need to connect the sensor to an electrical outlet. For the A100c meter each pulse represents a 1000th of a KWhr of 1Whr of energy passing through the meter. They use solid-state transistors to allow power to pass through in one direction when activated by a magnetic field passing across them. Create the utility meter and sensors by adding following configuration to your configuration.yaml file. In order to do that you will go to Home Assistant service call helper (in the developer tools), go in yaml mode and use these: * The MySensors Arduino library handles the wireless radio link and protocol This article will provide you with a walkthrough on how you can build a water usage meter sensor that integrates with your Home Assistant for under 10 $/EURO without the need for any soldering or coding skills. I dont think the Pi will have issues because of this. 3-coil inductive sensor for flow direction detection. Selection of Meters The cool thing about using the utility meter sensor is that you can drill into reports. All MeiStream registers are prepared to receive the HRI-Mei.The HRI-Mei can also be mounted afterwards without breaking the meter's seal. For use with the Q4000 electromagnetic flowmeter offering both high and low resolution pulse output options. Im currently investigating this. Example meter A100C BS Single Phase Meter What is a pulse? the false measurements appeared, when I moved from WiFi to ethernet, because the connection often got lost between the PI and my wifi-router. This sensor will be able to recognize the piece of metal that is placed on the meter and will provide a pulse whenever a full cycle of the meter has passed. Wired M-BUS module for pre-equipped multi jet water meters mod.
