If you want to drop the price of equipment you can go down a level and use 433Mhz. Athough wifi chips have gotten cheaper lately and hopefully the smart home iot gadgets will keep dropping in prise.

Sonoff switches and plugs already cost less than $5, and they're all flashable with extremely good open source firmware. It's a great time to be a home automation hobbyist.

Please use a language like C, D, C++, or Python. They are much more lightweight. It takes hundreds of lines of javascript to be executed to do a single "console.log."

Printf implementations range from 300 to 1000 lines.

cout in C++ is not any smaller.

This is on top of the many hundreds to thousands of lines that need to be ran to actually make that text show up someplace.

The light turning to blue at 7am to indicate that sleep time is over is a nice touch.

Working in collectivities with young children, we'd have a sheet of paper with a sun/moon on each side, and every morning at 7 one of us would go in every room and turn the piece of paper around to let them know they could get out of bed and come to the common areas if they were awake.

Anyone interested in this sort of thing for their kids, I've found most hue lights to be too bright and I wanted a way more flexible scheduling ability. So I made my own and now sell them.

It does require any cloud besides ntp and just uses a local web interface. You can define relative events, like 15 minutes before bed is tv time, 5 minutes before is snack time, bed time is 8. If one night the kids are extra cranky and need sleep, simply adjust bed time and the others adjust too.

I've used em for years with my kids!

Sorry, should say does NOT require any cloud.

Very cool.

I do something similar with LIFX bulbs. (https://github.com/adamjacobmuller/lifx/)

I specifically have them configured to follow a f.lux-like curve for brightness and color temperature.

The only major thing I want to add is some kind of local control/override for the brightness. The curves work great 99% of the time but sometimes you do want BRIGHT even at 11pm. The dash buttons are a cool idea, but I don't like the look of them in a wall. Haven't found a great solution for that yet.

Agreed about the Dash button. I've moved one of the rooms away from that to a doorbell attached to a Pi Zero. I also picked up a Voice Kit (https://aiyprojects.withgoogle.com/voice/) for $10 at Microcenter, and I'm playing with what that could offer.

If you the room is near a server you have in the house (like a Pi running Pihole), then Bluetooth buttons (like Puck.js) unlock a lot of potential for you too.

Well done! This is very impressive!!! You're 100% right that the Hue lights don't get nearly dim enough.

I'm sorry I didn't see your product sooner. More parents should know about your this - I'll make sure to spread the word whenever possible (:
