Started a couple of months ago a Home Automation Project. All DIY, No ready made accessories. For instance ESP32's, ESP8266, relay boards, diy PCB's, making movement and light sensors, pressure pads for stair lighting- you name it im making it for all round HA!!!! Even door locking/unlocking with fingerprint and voice sensors!! The only thing i bought to control everything is 3 5th generation Alexa's and Phone apps
