This is the next one in the ESPHome How-to Series 1. Hope this makes sense…
Here I am going to talk about installing ESPHome Add-on into Home Assistant. Before I go on, I wanted to make sure it is clear that this option works if you are running a HA supervisor. So, if you are not sure that is where you need to start. If you are using a Home Assistant device then it has a supervisor. A quick way to tell is to look for the Add On option under Settings
So, click on the next step is simple. Click, button and find ESPHome add-on as shown below.
In there are currently three options. Use ESPHome one for released version of ESPHome. The other options are for non-released versions. They may not be as stable as the released version. However, there may be a reason you would want to use them so decide which one you would like to use. Below, I have added some great sources that expand on this post. Enjoy!!!
