€18-36 EUR / hour

I'm looking for someone to develop a circuit board for me. Tasks to be taken over by the board: - Read out SML data from a smart meter via infrared. - Preparation of the SML data in JSON. - active energy on L1,L2,L3 - total active energy - Sending the encrypted JSON file to the web server. -Battery on the back that can be charged inductively. -USB interface for charging the battery (alternative to inductive charging.) Installation: The device should be set up by holding a flashlight or mobile phone light to the device. The status of the device should be signaled by a green / yellow / red LED. Green (Ready) Yellow (Working) Red (Error). Then you have to connect to the device with the mobile phone app (Bluetooth). The device is then connected to the WiFi. Then a version check of the firmware should be carried out with the server. If the firmware is up-to-date, you should be asked to plug the device into the smart meter. Now the device should send all the data that are output by the smart meter to the web server. The web server and the app will be developed at a later date The device is intended for the German market and should be able to work with the most common smart meters. Best Regards Valentin

Hi, I am Electrical and Electronics Engineer with 14 years experience in micro controller programming and PCB designing and hardware assembling. I have worked in smart meter development and also energy meter data reader using IR development. I can develop this using ESP32 chipset, which is 32 bit arm micro with bluetooth and wifi support and Arduino programming platform. Your title says "PCB circuit board " but your description says PCB designing, PCB board manufacturing and firmware development. Do you have any schematic? Have you selected any micro controller? Have you selected any Wifi chip set? We can discuss Regards Senthil Chennai,India

Hello, I read your project description thoroughly and it got me really interested. I am experienced in electronics and PCB design, microcontroller programming, as well as Android programming, so I think I would be well qualified for your project. For instance, I recently completed a larger end-to-end project in which I had to design a LED digital stroboscope from scratch. It included making architecture choices, choosing the suitable components, designing the PCB, writing the microcontroller firmware and the Android companion app, which could remotely control the device. The stroboscope is powered by a Li-Ion rechargeable battery, so I also had to take into account the usb charging and battery level monitoring. If interested, you could read more about this project in my portfolio. If you would like to further discuss your project, please send me a message. Thank you, Emanuel
