Any chance you have or could post pics of those custom HA controllers? Seeing custom interactables and how they integrate with ppl's environments are always suuuuper interesting
Something I've been doing is making an automated hydroponic tent. Temp, humidity, EC sensors and a few servos to control nutrients all feed into an esp32 + servo controller and broadcast data through a local webapp. Just need to add a camera for timelapses and remote viewing.
I have a bunch of Home Assistant controls using a variety of custom controls and cases.
I have a custom version of Seeed's ESPClaw (https://github.com/Seeed-Projects/espclaw - there are a lot of other ESP Claws too) with a case.
I'm working on a Tamgotchi-style mini-game device using ESP-NOW to connect with nearby devices.
Lots of other random projects at various stages of development.
