EspHome Device Randomly Disconnects from Wi-Fi

While I built my Air Gradients a while ago, there was a bug with their wifi connections that I’ve been chasing for a while. They drop off the network and don’t reconnect, forcing me to hard reboot them by cutting power to get them to reconnect. I think I’ve finally figured how to get them to at least be mildly stable and keep them from disconnecting for days at a time.

Using ntfy.sh from Home Assistant

While surfing Reddit one day I ran across a post about Unified Push and setting up ones own self hosted push notification system. A push notification system that can be self hosted and isn’t owned by any of the big tech companies, which I’m all for. So I decided to test it out by setting up home assistant notifications through it. While here I won’t be installing and setting up my own ntfy.sh server right now, I will probably be doing that part in the future.

Network Layout

Here is a rough guide of how I have my network laid out. I haven’t really documented it before, so hopefully this covers the major points. I use a number of VLANS in my network to keep the IOT devices from being security threats, and prevent security devices from being able to access the internet (like security cameras).

I will write up a longer guide later on when I have some time, for now the short of it. The hardware is mostly Unifi gear with a Unifi controller running on my Proxmox host. This is the same host I run home assistant on (all virtual machines). The Unifi controller lets me configure my whole network in one pane of glass, its a bit of a pain at times, but for me the convenience has outweighed the higher price and limitations so far.

Fixing network problems in HASS

Recently I have been working on fixing the configuration issues in my home assistant installation. I run the supervised mode on an Ubuntu VM that I setup myself with some scripts (since it’s not supported by the official installer). Due to this, I encountered a problem with network manager in home assistant that caused home assistant to lose Internet access (so unable to download updates) even though the VM has no problems accessing the Internet as a whole.

Home Assistant Wall Tablet Display with a Fire HD8

I have wanted to add a tablet to control home assistant from for a while. I originally started by using my Nexus 7 2012 as the machine, got WallPanel installed, and found out that the embedded browser in that version of Android was too out of date and crippled to run the home assistant webui. So I decided to pick up an Amazon fire tablet for cheap to try using. I figured if I liked using it, I could use a better tablet in the future (or go through the effort of rooting the tablet and installing regular Android on it).

The Indoor Air Quality (UK) HACS Integration and Sensor

Now that I have a number of AirGradient sensors around my house, I have all sorts of data I can make use of about the air quality inside it. I now have to figure out how to make use of all that data. Creating a single unified data point for general air quality based on the AirGradient data is the first thing I’m going to do. To do this, I’ll make use of the IAQUK HACS integration.
