Home Automation

There is a decent amount of home automation running at the Vondruska house. I’ve gotten quite a few inquries on everything that is running. I try to keep this updated as much as possible.


No 100% reliance on cloud services unless absolutely necessary. That allows me to tolerate my home internet connection going down, a cloud provider having a bad day, some sort of service outage or the manufacturer deciding to end support for the product.

That being said, I don’t think the cloud is a bad thing. It typically provides convenience and many times, improves accessibility. During an outage, it could be more challenging to complete a task (i.e. asking a Google Home to do something) but still able to execute it via a web interface (i.e. Home Assistant)

Services used

Here are the services (and some hardware) actively running to make it all works:


Everything in this setup runs in a container. Hosted on a Raspberry Pi 3B+.

Home Assistant

Home Assistant is the central point where all IoT endpoints integrate with. Essentially the IoT hub.

The configuration used to be under source control and deployed via GitHub Actions. Home Assistant has been migrating towards UI Configuration making it harder to merry the two ecosystems together. I rarely modify yaml files now.


MQTT broker. This allows many devices like the 2GIG sensors, Sonoff outlets and freezer temperature to push messages to subscribers, like Home Assistant, in a decoupled way.


Uses the RTL-SDR USB dongle to detect and push 2GIG sensor events (door open/close, motion detector, etc) into MQTT.

Tempy is a temperature monitor that I built using an ESP8266 and a DS18B20 temperature gauge. Reports data via MQTT over WiFi.

We are an Android household so there isn’t much reason for HomeKit. Yet thanks to unifi-protect-homebridge, Unifi Protect events are available in Home Assistant.
