What’s the purpose in having a sensible house in the event you can’t rely on it? It’s best to believe that your Residence Assistant setup will “simply work,” identical to a dumb house would. In pursuit of this aim, you would possibly have to make a couple of govt choices and investments alongside the way in which.
(Energy-over) Ethernet in every single place
I’d hazard a guess that the majority gadgets in your good house are wi-fi, which begs the query: why is Ethernet so necessary? The reality of the matter is that wired networks will all the time trump wi-fi ones when you might have the choice, whether or not you’re constructing a easy house community or fleshing out a sensible house.
For Residence Assistant particularly, opting to attach your server to the community by way of Ethernet cable lays a stable basis. Wi-Fi can be patchy in terms of coverage, is affected by issues just like the climate or your neighbor’s house community, and the community can grow to be congested as you add increasingly more gadgets. The extra gadgets you’ll be able to wire in, the higher.
That is very true on the subject of high-bandwidth gadgets like video cameras and good doorbells. One of many advantages of a Residence Assistant server is the power to use solutions like Scrypted to share camera feeds or add-ons like Frigate as a linked community video recorder. Continually transferring high-resolution video streams throughout the wi-fi community is a good way to decelerate gadgets that can’t make use of Ethernet.
On high of this, Energy-over-Ethernet (PoE) signifies that a single cable can be utilized to energy gadgets and switch information from them. With a set of PoE cameras, a PoE doorbell, or perhaps a PoE transmitter on your mesh community, you’ll be able to kill two birds with one stone with a good run of cable and a PoE injector.
Add or strengthen mesh networks
To additional scale back your dependence on Wi-Fi, add a mesh community designed particularly for good house networking. Applied sciences like Zigbee, Thread, and Z-Wave assist you to talk with low-power gadgets like switches, plugs, sensors, and thermostats utilizing a devoted mesh community that’s separate from Wi-Fi.
This avoids congesting your wi-fi community, leaving you with loads of router overhead to deal with smartphones, laptops, and different “true” wi-fi gadgets. All of those options use mesh networking, with most powered gadgets (like switches and good plugs) performing as middleman routers that broaden the vary of the community.
Which of those you select comes down to private selection. Zigbee has been across the longest, it’s comparatively low-cost, and there’s a devoted Residence Assistant radio within the type of the ZBT-2 to select from. Thread is the most recent, with the fewest variety of gadgets out there at current, however one that appears to grow to be dominant sooner or later (it too may be deployed with a ZBT-2). Z-Wave trades bandwidth and latency for vary, with adapters like Residence Assistant’s ZWA-2 able to speaking with gadgets a mile away.

The Residence Assistant Join ZBT-2 helps each Zigbee and Thread, though it have to be arrange to be used with both one of many two protocols. It presents 4x the responsiveness of the earlier mannequin, and is designed to be simple to open for modding, with accessible pins and pads.

The Residence Assistant Join ZWA-2 Z-Wave antenna connects to your Residence Assistant setup by way of a easy USB cable. Providing almost a mile of vary from the hub, you’ll be able to join Z-Wave gadgets even from outbuildings in your property to your Residence Assistant setup with this hub.
If you have already got a mesh community, you would possibly need to think about strengthening it by adding a few powered nodes in the form of smart plugs to cover any dead zones.
Ditch the reminiscence card (or change server fully)
The Raspberry Pi is likely one of the best methods to rise up and working with Residence Assistant since you’ll be able to simply write a Residence Assistant OS picture to a reminiscence card utilizing the official Pi imager software. The one-board laptop is succesful, power-efficient, and sufficiently small to suit nearly anyplace. You may wire it in by way of Ethernet, and broaden capabilities with radios that join by way of the USB ports.
Except you’ve gone out of your method so as to add an M.2 HAT+ to your Pi, you’re most likely working Residence Assistant by way of an SD or microSD card. Whereas this isn’t as risky as it once was, it’s nonetheless not a fantastic concept. Along with being slower than solid-state storage, detachable storage isn’t designed to handle the stress of frequent read-write cycles related to a sensible house server.
When you may add an M.2 drive comparatively simply, switching away from the Raspberry Pi and in the direction of a mini PC may be the very best resolution. You may run your Home Assistant server within a virtual machine like VirtualBox or ProxMox, with extra overhead out there (particularly RAM) in the event you want it. You may also run different software program alongside Residence Assistant, together with roll-your-own cloud storage and music-streaming services that can save you money.
You may then put your Pi to good use by repurposing it for an additional challenge.
Static IP addresses
Some gadgets that connect with Residence Assistant over your community, be they wired or wi-fi, are depending on an IP tackle assigned by your router. By default, these gadgets are assigned IPs dynamically. Once you restart your router or the gadget drops off the community, the following time it connects, it might be utilizing a distinct tackle.
Whereas many gadgets additionally use a hostname as an identifier, together with your server itself (that’s most likely http://homeassistant.native:8123), many profit from a static IP that doesn’t change. If you happen to discover gadgets generally disappear from Residence Assistant and grow to be unavailable, reserving an IP (and pointing Residence Assistant to it) is a stable first troubleshooting step.
Personally, I’ve arrange a static IP for my Residence Assistant server itself since I discover that the hostname generally doesn’t resolve or takes longer than I’d like. In contrast, 192.168.0.208:8123 by no means fails me. Different integrations rely on a static IP tackle to work. I’m within the strategy of including an air con controller that specifies {that a} static IP have to be used within the documentation.
You may configure static IP addresses for Home Assistant utilizing your router by reserving an entry for the MAC tackle of the gadget in query.
A Residence Assistant Cloud subscription
Configuring distant entry on your Residence Assistant server may appear trickier than it’s value in the event you’re not aware of VPN tunneling or opening ports and encrypting your server. If you happen to’re in search of one other approach to entry your good house server when you’re away from house, think about a Residence Assistant Cloud subscription.
Join your Residence Assistant server to your Nabu Casa account and log in together with your cell gadget. Now you can get pleasure from distant entry with out having to configure something or rely on third-party DNS companies or VPN suppliers. On your cash, you’ll additionally get cloud storage for backing up your Residence Assistant server to the web.
Turning on Residence Assistant backups is straightforward, however ensuring they’re secure it doesn’t matter what is a bit of tougher. If the one place you’re storing your backups is on the machine that runs your server, you’re taking part in a dangerous sport. One resolution is to jury-rig your own cloud storage solution, the opposite is to export on to Nabu Casa’s servers with Residence Assistant Cloud.
However maybe essentially the most underestimated function of a Cloud subscription is the power to make use of Google Assistant or Amazon Alexa to deal with your voice requests. You may also use Residence Assistant’s personal cloud-based Help mannequin in the event you’re feeling let down by the offline version.
With the brand new yr upon us, I’m additionally taking the chance to examine some problems with my Home Assistant server and correct course.
