PCB circuit board

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.)


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
