Home Assistant is a free and open-source home automation software written in Python with a focus on local-control and privacy. It has a very wide range of device support, and, as of October 2023, it features support for over 3000 modular plugins or add-ons with system integrations to different IoT technologies; systems and services are available as “integration components”. Actions, such as switching ON/OFF lights, are triggered by automation, voice commands, mobile apps, or controls on the Home Assistant web-based front-end user-interface. In this step by step guide I will show you how to install Home Assistant on your Synology NAS using Docker. You can also use HOOBS or Homebridge for your smart home devices.

💡Note: This guide works perfectly with the latest Homeassistant 2025.5.2 release.

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.
