We want to use ESP32 for our project 1. COMMUNICATES TO CLOUD: Firmware for Data upload to AWS IoT Hub​ via MQTT 2. READ SENSOR DATA: Firmware for data write communication from sensors​ 3. COMMUNICATES TO LOCAL NETWORK: Communication with Mobile APP

Need a simple tool to monitor one SNMP and MQTT-based monitoring tool. You can use any stack to create this software. It needs to have web interface. I want to monitor 2 devices one using SNMP and one using MQTT.

I have a functional ESP32 MQTT code and would like to add another functional ESP8266 code. Both codes suppose to work at the same time. A previous developer did this task but neither MQTT or firebase NOT working, maybe they in conflict or something else?

The project consists of connecting ESP32+RFM95 nodes that have sensors (you don't need to program the sensor, just the communication) to a lora gateway, either multichannel or a packet forwarder (a dual channel gateway). Not necessarily using TTN. The data must be sent to the cloud and the parameters sent by the nodes must be displayed. Proposals are accepted.

I have a Unity project where I need to make some changes. 1. Add 4 possible combinations, right now you only have 1 possible combination. When the merge is complete, the completion message appears for a few seconds and then goes away. 2. Save the project so that it can be opened from a raspberry and automatically, as soon as it starts. 3. When completing each combination, it sends a different mqtt status and activates a relay The Unity Project. We have all codes and files that appears in video

I selected an opensource app that connect to IoT smartwatch. The data are saved in a database file on the phone. I need a developer that add the choice to send directly the data via MQTT to a broker. The MQTT message is a JSON string with a few fix tags and (TIMESTAMP, VALUE). It is required to deliver the source code. The projects should require further customization. They will be considered step-by-step upon satisfaction on both sides.

We require the following experience: • Production Linux system administration (GCP cloud systems a plus) • publish/subscribe messaging (MQTT preferred) • docker+kubernetes (Locally hosted Kubernetes a big plus) • automated deployments+ CI/CD (Preferred GitLab, others okay) Nice to have: • application and server certificate management • API service development • HPC cluster job management

Hi, I am making a simple nodered flow to publish data via google forms to a google sheet. I have attached a project document with concrete examples. I will also have a live broker with contiuous messages to program while doing on real data as I think that is needed. Basically, I am trying to do the following : Parsing the message is done in nodered. I like nodered for its visual programming for data flows, especially live data flows. I am thinking a prototype could be built in approx 5 hours. After this prottype I will have another 8 hours for optimisation inside google sheets by adding pivot tables and simple filter functions.. If this is successfull I have more work. we could also use this flow: https://flows

...records water consumption and the app presents this data in the form of a bar graph. 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 ma...
