The home automation device I’m using is smart bulbs, which the application should be able to monitor and control. I would also like the app to be able to schedule operations, as well as monitor energy usage. If you think the challenge is something you’d be interested in, please reach out and let’s discuss further details.

    i want to make a GPS tracker PCB that will connect to my server using either TCP or MQTT. To achieve this, I'm considering using a main chip like the ESP8266, ESP32, or ATmega328. Additionally, I'll need two other chips or modules: one for GNSS/GPS and another for the SIM data connection. My goal is to achieve accuracy comparable to the Chinese GPS trackers available on AliExpress. I've looked into Quectel and Simcom, but there are numerous options available,i want some combination that offer performance and cost-effectiveness. you can suggest different chips if u think that they should be used. pcb will have some other basic sensors but thats easiest part --only bid if u have experience with gps and gprs/lte

    i want to make a pcb that will get gps data and send to my server via tcp (or mqtt) so i want to add there a chip that i can write a code like in arduino : My suggestion is to use 1. esp8266 (or esp32) -( and then via tx rx to conntact the gps and data chip) 2. for GPS: gps neo m8n or 6m 3. for data connection sim8000 You can suggest me any other chip if you think we should use pcb need to have some other sensors to detected movement (if someone shake it or drop it) 5. also orientation ( so i can check if its upside down or up)
