Hello, I read your project description. I have 5 years of CTO experience in Fintech and IoT. I developed unattended POS, 4G Telemetry, Next Generation Vending machine and Image Processing with Artificial Intelligence projects with Python. I used real time, multi-tasking and multi-thread with Python. Especially in the Telemetry project, I actively used Orangepi and I2C, UART, Serial and TCP/IP communications. I exchanged data from vending machines with these. I save this data on Sqlite and send it to the remote server. Also, I used MQTT to communicate with brokers. I accessed the remote OPi's with the network I set up through the VPn server. I transferred all the data in ORA to remote servers via API and backed it up. I made a demonstration of this data from the Telemetry SAaS application on the remote server. You can start a chat for details. Kind regards

Hallo! I’m an enthusiastic self-starter, problem solver specializing in Software Architecture & front/back end development with more than 22 years of experience & good knowledge about alternative energy (planning). For the last 10 years I've developed my own redundant IoT solutions (ie. GEIA) from ground up (using: Python/Shell, Arduino, LinuxOS, RestAPI, APP, MQTT & OTA Update) & used ESP28266/ESP32 LoraWAN, Raspi, RockPI, OrangePI etc + hacked SonOFF (OTA) & Tuya products. I would love to work on your smart meter project - with passion :) My prototyping lab is also well equipped with Electronic parts & 3D Printing. I'm available for a video call to introduce myself, experience & explain some comparable reference projects. Cheers, June
