Intelligent remote water meter AMR NB-IOT MQTT/CoAP DN25mm. This leaves most of us in a position to require a plumber to install our own meter that has some kind of data output. Landis+Gyrâs advanced water metering solution enables the integration of water metering into the RF-Mesh, AMI network. 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! Common sizes are 3/4″ and 1″. Last ⦠Great post, and exactly what I was looking for help with. The MQTT gateway is basically a Ethernet Gateway with modified software which makes it act as a MQTT client. Here are the main things to look for: I settled on a stainless steel high definition meter with pulsed output from EKM Metering. Your email address will not be published. The sensor comes with three wires: red (5-24VDC power), black (ground) and yellow (Hall effect pulse output). 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. 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. topic "" in 0 home/water-meter data/v2/city-council-name/123456. Skip to content. Unfortunately that will probably cost more than the meter itself. To use your MQTT sensor in your installation, add the following to your configuration.yaml file: It emits an infrared light and detects the reflection. 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? Also, the devices are equipped with an MQTT client interface and can easily be configured to transfer data to a third-party MQTT server and to manage the external load by the corresponding subscription. (In the case of the meter referenced above, it is one pulse every 0.075 gallons) We need to count these pulses and somehow push the data to Home Assistant. If it has a data output, it is likely closed and/or proprietary. The more utility data you integrate into the system, the better the potential automations become. The W5100 MQTT gateway sends radio network (or locally attached sensors) data to your MQTT broker. Watch Queue Queue Make sure that the data resolution or definition is sufficient. Some are ZWave which integrate easily and others have a simple pulse output you’ll need to interface yourself (see below for more). (It also allows us to independently verify utility readings.) Configuration. Glad I read the comments. As I said, I have been using exec binding to fetch water meter value directly to openHAB item. Whenever someoneâs location changes, the Pi alerts the clock over MQTT, and it moves the 3D-printed hands with servos. To make the Pi’s environment easier to replicate, the major functions are running inside two Docker containers. To detect leaks and small flows, you want to be able to measure at least every 1/10 gallon of flow. Almost all the meters in the $150 range work by having a photocell detect the movement of the mechanical dial on the face of the meter. The new development provides a standard method of communication for sensors and devices to reliably communicate data across networks, brings Linortek IIoT Solutions to the next level. Sorry I’ve been somewhat behind on responding to comments here, but glad you figured it out! (They were helpful in answering my questions and had prompt shipping.) (In fact, if you have an existing meter with dials like those shown in the photo, you may be able to just purchase and snap on the optical detector and avoid the costly steps outlined so far.) Each pulse is approximately 2.25 milliliters. It is worth checking out though to see if yours is one of them.) This sensor will track a source sensor values, automatically resetting the meter based on the configured cycle. 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. In addition to measuring usage, having water flow information in Home Assistant allows you to come up with some unique automations. The new MQTT binding can coexist with the old MQTT openHAB 1.x binding (but I really do not recommend this setup). Published author and historian. I wanted more control, so I decided to build a pulse counter and data node using a Raspberry Pi. Otherwise, the initial state will be undefined. I’ve pretty much settled on Home Assistant as my DIY automation platform. 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. If unsure, look on your water bill for the pipe size or ask a plumber. 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. Things used in this project . In addition to flow rate, I included some binary sensors for sustained flow and high flow as well as daily cost, which can be configured through variables. 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. Start by building the physical gateway by following ethernet gateway instructions.. Thanks! It`s ready to retrofit classical meters over pulse signal output from a meter or to be customized for integration inside a meter. I also want to see real time and historical usage on my various dashboards. 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.

This is much more efficient than trying to place water leak detectors all over the place. In some cases, newer water meters are equipped with a pulse output. You’ll want to run the script in the background continuously as a service. 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. 10 months ago. - - parameters according to meter type: - for o,s,e,m,r: serial baud rate eg. If unsure, look on your water bill for the pipe size or ask a plumber. Software developer and hardware tinkerer. Over a decade of experience as a technology executive and entrepreneur. Hi in South Africa we use liters,will i have to change alot in the code to get this to work. 9600 - for c: - positive value >0 = counter poll interval - negative value <=0 = debounce time (milliseconds) for irq driven counters - - prefix for Web UI and MQTT JSON payload. Using an ESP8266 and Si7021 sensor to remotely monitor temperature & humidity via MQTT. Notify me of follow-up comments by email. Keep in mind that all of your household water will be passing through this device before it reaches you! You signed in with another tab or window. If messages in this state_topic are published with RETAIN flag, the sensor will receive an instant update with last known value. Use the TCRT5000 IR Barrier Line Track sensor. Your email address will not be published. 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. Watch Queue Queue. More research uncovered a selection of meters in the $150 range that fit the bill. Alan. 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.

Thanks for posting your fix so maybe others can benefit. In recent years, the emergence of intelligent gas meter and intelligent water meter makes automatic meter reading possible. Clone with Git or checkout with SVN using the repositoryâs web address. I suggest using a non-zero Pi with Ethernet built in, but any Pi can work as long as you place it on the same network as your Home Assistant installation. However, for us DIY hardware tinkerers, that would be too easy. Here are the main things to look for: Make sure the meter is designed for the size of your incoming water main. The utility meter integration provides functionality to track consumptions of various utilities (e.g., energy, gas, water, heating).. From a user perspective, utility meters operate in cycles (usually monthly) for billing purposes. 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. Buy the best and latest water flow meter sensor mqtt on banggood.com offer the quality water flow meter sensor mqtt on sale with worldwide free shipping. I’ll be adding additional posts about home automation platforms in general, but for now I want to concentrate on how to connect a water flow meter to Home Assistant. 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. I also like that it is written in Python and includes support for custom dashboards using HADashboard. Counting pulses is a pretty basic task for the Pi and the core counting code has been posted below. Contribute to bram2202/mqtt-watermeter development by creating an account on GitHub. This video is unavailable. MQTT Temperature and Humidity Monitor for Home Assistant. Common sizes are 3/4â³ and 1â³. 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. Beginner Full instructions provided 1 hour 23,764. I misread that as 'wattmeter' and saw mains wiring colors and I was like noooooooo! What format is the data output? # MQTT Broker When it comes to MQTT enabled devices, like your WiFi wall plug or custom Arduino or ESP8266 solution, you first need to take care of a very central aspect, the MQTT ⦠davidjb / configuration.yaml. (A recent article on rtl-sdr.com explains how you can intercept and decode wireless utility meter data, but only a few meters are supported. In fact, every pulse is saved in the database so that intricate usage analysis can be performed if desired. This mqtt sensor platform uses the MQTT message payload as the sensor value. {% set data = state_attr("sensor.water_meter", "data") %}, {{ (data|selectattr("parameter", "eq", "backflow")|first)["value"] }}, {{ (data|selectattr("parameter", "eq", "tamper")|first)["value"] }}, sensor.water_usage_mains_weekly_previous_kl, sensor.water_usage_mains_monthly_previous_kl, sensor.water_usage_mains_yearly_previous_kl, .entity div:last-child { font-weight: 200; font-size: 2.5rem; letter-spacing: -.22rem; text. MQTT-based water meter configuration for Home Assistant - configuration.yaml. Maybe I need to run the dial eye on another instance, since my water meter is in the ground out near the main road⦠It may also be too far from the rest of your equipment to be practical, as it was in my case. I do not recommend using the same Pi that is running Home Assistant, since we don’t want anything slowing down the measurement activity. added this line under connect, in watermeter.py, client.username_pw_set(username=”example steve”,password=”password”), Hi Wayne, More research uncovered a selection of meters in the $150 range that fit the bill. Make sure the meter is designed for the size of your incoming water main. Sign in Sign up Instantly share code, notes, and snippets. 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. By counting the pulses from the output of the sensor, you can easily calculate water flow. iPERL meters use a unique technology that provides unrivalled, sustained accuracy over their expected 15-year operational life. For that reason, I decided to only count the rising edge of the signal. 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. While it is not perfect, it has the right mix of features, simplicity and customization for my needs. ESP8266 based logger for analog watermeter. Don’t get a cheap meter designed for garden hoses and install on your water main. 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 Some meters have an external ZWave device that does the counting and data transfer for you. 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. Also note that due to the nature of the mechanical source of the data, when water flow stops, the pulse can be either high or low and remain that way until the next flow activity. Cloud server Is there specific reason why you want to use MQTT? The meter should be made from a sturdy but safe material. The hall effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry.
