15M smart home power users and automation-heavy households

The Problem

Smart home users often need small, specific automations that mainstream devices do not handle well: gentle door alerts, ambient-light-based lighting, projector power detection, low-voltage triggers, and dimmable module control. They end up cobbling together Raspberry Pis, IR repeaters, sensors, and hub rules, which is unreliable and too technical for most households.

Potential Solution

Build a small modular sensor bridge with plug-in inputs for contact, light, voltage, USB power, and IR state detection, plus outputs for learned IR/RF commands and hub-compatible events. A companion app lets users configure gentle alerts, thresholds, dimming behavior, and automations, then exposes everything cleanly to Google Home, Home Assistant, Alexa, and Matter-compatible hubs.

Why Now?

Smart homes now commonly include dozens of devices, but edge-case sensing and gentle safety automations remain underserved. Matter adoption and growing Home Assistant usage make a cross-platform sensor bridge more practical and valuable.

Light modules that dim?

Jun 9, 2026

I have a number of hubs and would like to start adding light modules. I don’t see anything that mentions dimming on them. Am I looking up the wrong thing or is it strictly on/off? I appreciate your help.

Remote code repeater w low voltage sensing

r/homeautomationJun 9, 2026

Does anyone have any ideas on how I can put together a module that does the following: \- Repeats a learned remote code \- Senses a low voltage value say below 9.9V \- Upon sensing the low voltage value which is programmable or set able via potentiometer. Will trigger the remote code to TX. Practical use is to trigger a remote start generator to start when my travel trailer sinks below a set voltage. I was once upon a time a custom car audio and Home automation crew chief for a retailer in the late 90’s and early 2000’d so I am at least capable so any suggestions help even if fairly difficult.

How do I get my projector, to tell Home Assistant it is on?

r/homeautomationJun 9, 2026

So I‘m working on a script im HA to call forth what I call „work mode“. One important aspect: I want home assistant to check if the projector is on and turn it off if it is. Therefore I used a PI Zero and taught it the IR pulse to shut off the projector. That part works. But: if the projector isn’t on, it will turn on… that sucks of course. So I need to let HA know IF the projector is on? My idea was to use the usb service outlet on the projector, or a light sensor added to the PI… don’t I have something at home I can use? Projector: ACER H6555AKi Beamer(Full-HD, 5,200 I know it can be solved with a socket etc. but I‘d rather not buy something. Ideas?

Ambient light sensor to work with Google Home?

r/homeautomationJun 9, 2026

Ok, my son convinced me to go with Google Home to manage all the devices in the home we bought three years ago. Fast forward to today and we now have more than 50 devices with many capabilities mostly controlled by Google Home. We’ve also established quite a few automations in Google Home to that extent that the house practically runs itself with one glaring exception - on overcast and rainy days, the interior rooms get dark and we would like technology to address this issue. We’re looking for an ambient light sensor that can trigger a Google Home automation. Can you suggest a product for this purpose?
