The data is transferred as sensors to Home Assistant using MQTT. For instance, if the system knows you are not home and water flow is detected, it can send you an alert or even shut off the main valve. Linortek Launches iTrixx® Wireless Equipment Hour Meter with MQTT Protocol. This is much more efficient than trying to place water leak detectors all over the place. Maybe I need to run the dial eye on another instance, since my water meter is in the ground out near the main road… Thanks! Is there specific reason why you want to use MQTT? Last … Because the gas meter and water meter can not be connected frequently, the intelligent gas meter and water meter will adopt the low power WAN Solution so as to achieve long-term use without frequent battery replacement. Don’t get a cheap meter designed for garden hoses and install on your water main. The sensor comes with three wires: red (5-24VDC power), black (ground) and yellow (Hall effect pulse output). You want something that will last and not leak. added this line under connect, in watermeter.py, client.username_pw_set(username=”example steve”,password=”password”), Hi Wayne, Watch Queue Queue Once the meter is installed, the next step is to interface the data output with Home Assistant. To make the Pi’s environment easier to replicate, the major functions are running inside two Docker containers. Special settings for operating the device are not necessary, the meter connects to the cloud data server by itself and provides bi-directional exchange of information. MQTT-based water meter configuration for Home Assistant. Alan. It emits an infrared light and detects the reflection. In addition to measuring usage, having water flow information in Home Assistant allows you to come up with some unique automations. topic "" in 0 home/water-meter data/v2/city-council-name/123456. Hi any idea how to change the user name and password, trying to connect to Hassio mqtt and not allowing it, When publishing to Hassio the mqtt broker uses a username and password,how can i alter it to my user name and password, exactly what i was looking for, unable to use it, as Hassio needs a password and user name, big pity,:( as i used mqtt explorer and it works like a dream, would you beadle to add that into the settings page? Published author and historian. What format is the data output? It is worth checking out though to see if yours is one of them.) If you have the skill, you could save a lot of money doing it yourself but it is definitely not a project for amateur plumbers! Here is one dashboard I have running on a small LCD display in my kitchen: The water utility meter already installed in most residences is probably not something you can pull data from directly. Start by building the physical gateway by following ethernet gateway instructions.. I wanted more control, so I decided to build a pulse counter and data node using a Raspberry Pi. Use the TCRT5000 IR Barrier Line Track sensor. However, for us DIY hardware tinkerers, that would be too easy. The more utility data you integrate into the system, the better the potential automations become. Unfortunately that will probably cost more than the meter itself. IoT water meter is a tool for direct measurement of water consumption, which is used as a part of water metering system, water telematics system or as a stand-alone (autonomous) solution for water consumption monitoring. Hi in South Africa we use liters,will i have to change alot in the code to get this to work. If it has a data output, it is likely closed and/or proprietary. Whenever someone’s location changes, the Pi alerts the clock over MQTT, and it moves the 3D-printed hands with servos.

I misread that as 'wattmeter' and saw mains wiring colors and I was like noooooooo! Your email address will not be published. As I said, I have been using exec binding to fetch water meter value directly to openHAB item. The MQTT client utility is a Java™ application with which you can explore the features of MQTT, that is, connecting to a queue manager, and publishing and subscribing to topics. NB-IoT Smart Water Meter is a stand-alone battery-powered solution with NB-IoT and Bluetooth connectivity designed as accurate water consumption monitor with embedded analytics as well as a leak detector. Water usage data is a great addition to Home Assistant and provides a lot of insight into how your household and its appliances use (and waste) water. This sensor will track a source sensor values, automatically resetting the meter based on the configured cycle. I found some advanced meters that simply clamp onto the exterior of the water main and read the flow inside the pipe through ultrasonic analysis, but these were very expensive ($1,200+) and did not have enough sensitivity to measure small flows. The meter should be made from a sturdy but safe material. Skip to content. Water communication modules are retrofitted onto existing or new water meters, log consumption values for each interval and transmit data across the network four times per day to support advanced capabilities such as leak detection, reverse flow, and anti-theft. Otherwise, the initial state will be undefined. Sign in Sign up Instantly share code, notes, and snippets. Sorry I’ve been somewhat behind on responding to comments here, but glad you figured it out! Common sizes are 3/4″ and 1″. If messages in this state_topic are published with RETAIN flag, the sensor will receive an instant update with last known value. Instantly share code, notes, and snippets. Thread, MQTT, 6LowPan Challenge • The water meter provides monitoring of the primary inlet • Interoperate with thread devices and Nest ecosystem Linux Gateway • Off-the-shelf Hardware (beaglebone Black) was used with the Linux application(cpp), Silicon labs radio chip for Thread protocol, MQTT to connect to the server. I Create my own project using Water meter sensor using arduino uno + LoRa Shield Dragino my sketh code using this code: #include #include int count=0; int device_id=6667; // ID of this End node /* Liquid flow rate sensor -DIYhacking.com Arvind Sanjeev Measure the liquid/water flow rate using this code. You’ll want to run the script in the background continuously as a service. This type of metering provides a “pulsed” output which is basically just a switch closure every time a certain amount of water passes through the meter. Landis+Gyr’s advanced water metering solution enables the integration of water metering into the RF-Mesh, AMI network. iPERL® (International) are next-generation, high-performance, solid-state smart water meters with integrated bi-directional communications capability. In recent years, the emergence of intelligent gas meter and intelligent water meter makes automatic meter reading possible. Originally I used HTTP sensors but the overhead was higher than it needed to be and MQTT seems to be a more natural fit for the tiny real time data being transferred. I should probably get more sleep, lol. You signed in with another tab or window. | Shopping Australia MQTT Temperature and Humidity Monitor for Home Assistant. September 21, 2020 at 11:30 AM EDT. The new MQTT binding can coexist with the old MQTT openHAB 1.x binding (but I really do not recommend this setup). Thanks for posting your fix so maybe others can benefit. However if you have an older power meter without a pulse output, then you might be able to use one of the options below to sense your water consumption. I decided to get overly fancy and installed the Nginx web server as a front end for meter configuration settings and SQLite for the back end. You can use the client utility to verify your telemetry setup (for example, when you create a telemetry channel), or the client might serve as an aid when you are developing and debugging applications. Using an ESP8266 and Si7021 sensor to remotely monitor temperature & humidity via MQTT. More research uncovered a selection of meters in the $150 range that fit the bill. just a username and password, i would ask for current readings ect but suppose that is pushing it , managed to figure this one out, working like a charm Watch Queue Queue. The clock has some interesting granularity to it as well. It`s ready to retrofit classical meters over pulse signal output from a meter or to be customized for integration inside a meter. Note that the water meter output is basically a pulse width modulation (PWM) waveform with a duty cycle that varies with the water flow rate. (It also allows us to independently verify utility readings.) Software developer and hardware tinkerer. Configuration.
