After using NextDNS for parental controls, I've moved to a local AdGuard Home setup with OpenHAB integration for even better control over what my kids can access on our home network.
A battery operated catdoor opener & closer. It uses ESPHome running on an ESP8266 microcontroller in a 3d printed enclosure, controlled from OpenHAB. Now the cat waits for it to open at 6AM :)
My first WLED project and introduction to playing with RGB addressable LED strips. This is a 'mountain peaks' wall art design for my son's bedroom. Doubles as a handy reading or night light!
