My kids are sneaky when it comes to bedtime and my guess is so are yours. They don’t mean to be so mischievous, even after explaining to them that they have a big day tomorrow and need a good night's sleep, they still just want to play more 🧸. So after the night time routine and turning out the light, fifteen minutes later you’re pretty sure you can hear them rustling in their room or even sneaking down the hallway.
But wait! You have a smart home, you’ve got motion sensors in the hallway, automations on the lights, and lots of other smart home devices. There must be a way to track if the kids are actually in bed (not just in the room) 🛌.
You could put a camera in there, like when they were a baby in a crib, but now that feels more like an invasion of their slowly growing independence and privacy. You could try a motion sensor, but it won’t show if your kid is actually in bed, just that something moved in the room (maybe it was a pet and they’re fast asleep). mmWave sensor? Maybe, if placed in just the right spot, but we’re talking about a child’s room and the chance it gets bumped out of alignment is pretty high. You could try to make something custom yourself, but if anything goes wrong there's nobody to call to help 🤷.
So, what is your alternative?
Meet SlumberTek, a pressure sensing smart bed sensor made for Home Assistant users who want reliable, real time bed presence tracking. Discreetly hidden under the mattress, SlumberTek is a plug-in and forget solution. There are no batteries to change or charge, so once you set it up, SlumberTek gives you continuous tracking of your kid’s bed activity. SlumberTek lets you set up Home Assistant automations that respond when your child gets in or out of bed, and the sensor data can help you understand their sleep patterns over time. It’s even possible to use SlumberTek fully locally, so no internet required.
