And when it's inside butget I like in place of DI1 and DO2 an Opentherm connection like this part () because my current thermostat and boiler has already this connection. Program must be based on Tasmota or, when it not possible an simple web-based page to change the parameters. (optional with MQTT for some domotica solutions) When there are some questions let me know it.

Hello Hemant Liladhar R., I am looking for help getting MQTT working properly on a Raspberry Pi, running WeeWx software and WeatherFlow Tempest hardware.

we're working on a home automation system. It uses MQTT protocol to communicate between the devices. I need a cross platform app to do the same work. We've used this plugin on Cordova for Android and is working well: But IOS support is missing, so need to develop a working plugin for cordova on IOS

I need C developer to build a code for boards like ESP. The major features is web interface, support mqtt.

Implement the MQTT project with MSP430 using the ESP8266-01 module, I have 100$ and I want it in 7 days, DO not need a PCB design.

A single tab should be added in the Web application which will have the option to edit, save and display the new user data., Frontend is already there, only the backend part needs to be implemented.

...At this stage of the project, I need to implement the initial configuration of the ESP32 device using Bluetooth, as the link (), in addition, implement the MQTT to access the ESP32 device via MQTT Broker on the internet and the redesign of the screens. I developed the app's initial flow to make it clear what the app needs to check once it's started by the user, after that it's simple, the app already knows the ESP32 device via mDNS or MQTT Broker, with that, the app must do HTTP GET/POST via mDNS on the local wi-fi network, or via request/response topic on MQTT broker. The design of the screens is to better sectorize, hierarchize the information and make the information more user-friendly. The app is already launched, and I have the initial p...

Looking for an embedded engineer who can build firmware for the energy meter using HLW8012 and send the data to the AWS using MQTT. The hardware stack includes ESP32+SIM800L+HLW8012+Indicator Led's P.s: if someone can implement it using the M65 OPENCPU platform, preference will be given.

I need...program for hidden mesh communication over wifi + Bluetooth for ESP boards where one of the boards will be acting as MQTT Server + (MQTT Client for another MQTT Server) and in case the local MQTT Server (one of the boards) is offline, then the other boards will communicate through the mesh without affecting their communication and functions. All boards can be programmed OTA. The boards that have Nextion screen can update and send the graphic file OTA. Boards can communicate over Modbus (Wifi+serial) for the related points while the board with MQTT Server can report all the MQTT points over Modbus too. Web server with custom password for assigning the required parameters like wifi, MQTT, name, nextion file location for upload, arduin...

I need to visualize 2 sensors using aws-iot-core and grafana or google charts. Additionally i need to demonstrate a smart plug control which is connected also on same gateway. In near future we will develop a full solution which will include a web based dashboard and a mobile app. Is needed to be familiar with JSON, MQTT, AWS, javascript and Alexa. If you more familiar with GCP - google assistant is also an acceptable solution. Sensors are already connected to AWS and data are uploaded

Looking to subscribe to multiple topics on multiple brokers and store all data in a single SQLite3 database. Simple UI required for inputting brokers/topics. Script to ultimately run on Raspberry Pi.

I have a program monitoring my LiFEPO4 battery BMS via MQTT running on an AWS Lightsail Node.JS environment. I want a bit of help with the flow to fix some bugs. I also want to password protect my app , and also update my AWS Lightsail (Bitnami ?) VM to imporove its security. I envisage a Zoom call for about 1hr to discuss and hopefully fix most things.

A React Native app is functional today, but has some very minor bugs, and misses a few features. This initial small project will be used to verify if we can work together - If we can, I expect much more work over time on this project. You must have access to Android and iOS hardware, so that builds can be tested on device. Experience with MQTT protocol is a plus, as the majority of app communication happens through this protocol. However, it is not a strict requirement as much of this is already in place. See attached description of init...

I need a phyton code so I can use with conjuntion of CRONTAB -e so it can run every month and keep my MQTT running without any stopping

Hi Mestek, I saw that you can do a project similar to one I am interested in. I want to connect an Arduino Mega 2560 with a SIM800c module to AWS IoT core using the MQTT protocol with authentication and be able to send and receive messages between the Arduino and AWS. I am seeing that Mexico has very bad 2G reception, so I was looking into other modules with 3G or 4G as well. I'd like to know if you recommend something for this as well. Thank you! Leonardo

Hi, Thanks for reading. We have a project that has a number of elements which we are hosting on a web server. The elements include: 1. Asterisk ip PBX 2. Kamailio SIP Server 3. A database for the above 4. An MQTT Broker 5. A web server to support all the services. The system is an emergency call system fort he elderly and we need to be sure we have resilience We need a person to review from the outside and make recommendations on how we make the system scalable and robust. You will need knowledge in: - Asterisk - kamilio - PHP and web servers - MQTT Brokers This is a short project but we see further long term work in helping us as we add more features. Thanks for reading

We are looking for a developer for our Activemq ( MQTT ) project. He must be familiar with MQTT and also have experience with webRTC and P2P Messanger. The application should be written in Flutter/Dart for cross platform capability and for the native Android part Kotlin should be used. i.e. as much as possible Flutter/dart and as little as necessary Kotlin to get an optimal performance on Android He must use an Android phone himself to be able to test the application extensively with the team. He must have excellent documentation skills of his codes, so that any developer can very easily connect at the code level. He must be a good communicator and have very fast response times and take responsibility for his work. We work with Github & Slack

There will be 12 LEDs. During a round, each LED will light a single color out of three. These colors will be red, blue and white. The player will have three buttons to press and he will have to indicate which was the priority color. If it hits, it moves on to the next round. If you miss, the game is over. To make the game more difficult, at each round, during an interval of 5 seconds, the LEDs must flash faster and faster. I need this prototype ready in the next 12 hours.
