Is it possible to send sensor data from an ESP32 to a Raspberry Pi running ELK, all on a LAN? I'm also wondering if we can then send data from the ELK interface back to that ESP32. I've seen videos where were sensor data is sent to the kibana interface, but it requires having a current timestamp, which we won't have on a LAN. We could add real time clocks, I assume that would fix the issue?
I'm not incredibly well versed on ELK, and I've done a bit of googling to see if this exact set up has been done and have yet to find it. We're also wanting to add a couple different buttons that, when pressed, will push data to the ESP32.
I would certainly prefer doing this over building my own website.
