What kind of home automation?
I recently rolled my own environment sensing, from the ESP32 C code up to the web front end. I basically got it functional and have been using it daily.
That sounds awesome. What is the front end written in? I always struggle writing front end stuff.
I want to get there with ESP32 sensors but haven't had the motivation or energy to make it happen.
I have a few use cases in mind -- soil moisture sensors for the garden, temp monitoring for fridge/freezer, stuff like that.
But so far all my home automation / smart home / "dumb home on the internet" stuff has been off the shelf stuff... so pretty boring.
I struggle with frontend too, it was a super basic jinja templates with html and a plotly js applet that I just fed data to. Its ugly but functional.
I Started to re-write the server in Go, I have like 90% feature parity with postgres instead of mongo, but I need to figure out vue when I have a chance to make something a little nicer. I have an old obsolete ipad with a bunch of touch deadzones I'd like to load up in kiosk mode for a nicer data display.
I really liked the ESP32 ecosystem. I figured out the ESP-idf and really liked the build system and freeRTOS. The examples given are really exhaustive and super useful. I basically did format strings into static HTML headers to send the data to the server since it only has like 3-4 readings.
Interfacing with any common hobbyist sensor is mostly a matter of finding a basic C driver and adapting it for the ESP build system.
