Then I fell down a rabbit gap studying about folks utilizing spare telephones as good dwelling helpers, and as an novice tech hacker, I obtained concepts for a mission.
That Pixel now feeds sensor information into my good dwelling, doubles as a safety digital camera, and handles a few community duties. One of the best half? None of it wanted new {hardware}.
I moved my good dwelling off Wi-Fi and onto Thread, and my router lastly stopped crashing
Thread mounted the one good dwelling downside I could not troubleshoot away
A smartphone is a sensor hub you already paid for
One app, over 100 issues to automate round
Residence Assistant is the open supply platform that ties every thing collectively, and it runs by itself always-on machine, normally a Raspberry Pi or a small devoted field.
A telephone is packed filled with sensors, and a purpose-built good dwelling gadget would fortunately cost you for each certainly one of them.
Now, the previous telephone acts as a node that the server talks to, which opens good dwelling controls that work with Residence Assistant.
You put in the Residence Assistant Companion app on the previous telephone, level it at your server, and it arms over greater than 100 information factors.
Battery degree, charging state, gentle degree, connectivity, movement, the subsequent alarm you’ve got set, and rather more. Every one exhibits up as one thing you’ll be able to construct an automation round.
My favourite is the ambient gentle sensor. Each telephone has one. It is what dims your display, and Residence Assistant can pull a reside studying from wherever the telephone is sitting.
I positioned the previous Pixel on a shelf close to a window and arrange an automation that triggers the good lamps when the room gentle drops previous a sure level.
A standalone gentle sensor would’ve price me cash, however this one was already gathering mud.
Turning it right into a safety digital camera
Residence Assistant can learn the telephone’s video feed
The second job is a digital camera, and I typically convey this up first at any time when folks ask as a result of the payoff is very easy to see.
An app like Android IP Webcam turns the telephone into an IP digital camera, and the attention-grabbing half is that Residence Assistant picks it up by means of a built-in integration.
You get a reside video feed proper in your dashboard, plus the movement sensor the app exposes alongside it. And when that movement sensor exists as an entity, the automations principally write themselves.
Mine fires off a notification and flips on a porch gentle when it detects motion and no one’s dwelling. When paired with presence detection, the identical digital camera acts otherwise relying on whether or not you’ve got truly left.
It is one of many higher methods of repurposing your previous Android telephone I’ve tried, largely as a result of a safety digital camera is one thing you’d in any other case exit and purchase.
Nonetheless, it’s a must to watch out about the place you set the telephone.
If you’d like the telephone to observe a doorway or driveway, you are hanging an previous telephone someplace that is a bit uncovered, so a lined porch is best suited to this than leaving it out within the open.
Letting the telephone automate itself
A sensible plug retains the battery from cooking
Identical to you in all probability do, I had considerations about battery life. The previous telephone can solely final a number of hours, operating all these sensors plus the digital camera. However on the identical time, plugging it in to take a seat at 100% all day is the quickest strategy to wreck the battery.
I used to be happy to search out out that the Pixel might be a part of an automation about … effectively, itself.
Because the Companion app stories the telephone’s charging state, I can plug its charger into a wise plug and wire up an automation in Residence Assistant to chop the facility when the battery passes 80%.
When it dips under 20%, the identical automation can flip the good plug again on.
It might pull weight on your own home community, too
A telephone that is at all times on makes a good little server
Because the telephone is plugged in and on-line anyway, it could deal with a few community jobs. My favourite is Tailscale, which builds a small non-public community between my gadgets utilizing WireGuard.
I put it on the previous telephone and my every day telephone, and may now attain the previous telephone from wherever with out messing with port forwarding. It is helpful for monitoring my Residence Assistant setup whereas out.
The telephone additionally works as a small Community Connected Storage (NAS). A file supervisor like Strong Explorer turns it into an SMB server that exhibits up like a community drive in your different gadgets, which is okay on the 128GB telephone for backups and shared information.
With a server app like Plex, the identical telephone can maintain your media and stream it to TVs and laptops on the community.
I solely examined the NAS functionality as a proof of idea. I would not use this as a major backup system or media streaming platform.
A actuality examine earlier than you raid the drawer
It is not precisely a flawless setup
First off, the telephone wants everlasting energy, so you will desire a charger and a free outlet wherever you are going to place it.
You also needs to think about investing in a wise plug if you do not have one, so you’ll be able to run the charging automation mentioned earlier.
Additionally, Android is aggressive about killing background apps, which is strictly what you do not need when operating these apps is the telephone’s complete job.
You may want to enter the battery optimization settings and exempt the Companion app and anything that should keep operating.
It’s a must to take into consideration the telephone’s temperature too. Working the telephone all day is prone to get it heat (or extremely popular because it’s previous), so take the case off and let it breathe.

Why the drawer telephone gained
One factor I did not count on about this train was how little of it felt like a compromise. My first thought was that the previous telephone could be a funds stand-in for correct {hardware}, but it surely largely is not.
The telephone is not changing a Raspberry Pi as your Residence Assistant server, and the community chores are a bonus moderately than the explanation to do that.
Nonetheless, if in case you have a telephone in a drawer, and you’ve got been eager about good dwelling stuff with out committing, that is the most affordable strategy to discover out in case you truly prefer it.
