How to set up a smart switch to power your home (and what to avoid when you do)


img-2959.jpg

pros and cons

Pros

  • Can push and pull switches, for total bidirectional control
  • Nothing to wire into the mains and no electrician needed
  • Works with or without a hub.
Cons

  • Fitment can be a little fiddly at times
  • The VHB tape isn’t the best at sticking to curved surfaces
  • There’s only one spare bit of tape in the kit.

Home automation is a wonderful thing. I love that I can control so much of my life from my smartphone. But let’s be honest, this automation also made me lazy — so lazy that I now resent some of the simplest tasks.

Especially when that task is something as trivial as flipping a switch. Doubly so if some electrician put that switch in an awkward, hard-to-reach spot.

Well, good news: switch flipping is officially a thing of the past for me, thanks to SwitchBot

As the name suggests, SwitchBot is a device that presses switches for you. (Yes, we’ve reached the point in human history where we have robots for button-pushing. What a time to be alive.) 

Also: I set up a Firawalla Orange router at home, and it’s a bigger security upgrade than expected

And while I’m not usually a fan of sticking random attachments onto things, because, honestly, it feels like a Band-Aid solution, I also have to accept that replacing a switch isn’t always feasible. Maybe the switch is specialized, absurdly expensive, or attached to hardware that can’t easily be tampered with without voiding warranties (like the switches on the back of my 3D printers).

This is where SwitchBot comes in like a tiny mechanical hero. It’s a battery-operated “finger” (yes, really) that you stick to a switch. This finger then lets you control the switch through the SwitchBot app (iOS and Android). 

How it works

SwitchBot offers two modes of operation:

  1. Bluetooth Mode: The simplest and cheapest option. All you need is SwitchBot. You can control the device directly via Bluetooth, no extra hardware required.
  2. Remote Control Mode: For this mode, you’ll need to add a SwitchBot Hub to your setup. The hub connects the SwitchBot to your Wi-Fi network, allowing you to control it from anywhere in the world. (Because pressing a button from the other side of the planet is peak laziness, and that’s something I can get behind.)

SwitchBot does one thing, but it does it well.

Another thing I like about SwitchBot is that you don’t have to dive into the deep end right away. Start small with just a SwitchBot or two, and if you eventually need to press buttons from outside Bluetooth range (my test suggested about 75 yards with a clear line of sight, or 10 to 15 yards indoors), you can add the hub. 

The nitty-gritty details

SwitchBot is powered by a replaceable CR2 battery, which should last about 2 years if you use it a couple of times a day. The device is built to exert around two pounds of force, which is plenty enough to break a nail and bruise your finger (ask me how I know this…) and more than enough to operate most common household and office switches, unless you’re trying to operate something ridiculous. 

There was one light switch that SwitchBot couldn’t operate. On inspecting the switch, I found it was old and jammed with dust and dead spiders. 

SwitchBot is string enough to flip two switches.

You attach the SwitchBot using 3M VHB double-sided tape. You even get a spare piece in the box, in case your first attempt goes sideways, or you decide later to move the device. You can always buy more tape and cut it to fit. The kit also includes handy little attachments that allow the SwitchBot to pull a switch, not just push it. 

Oh, and if you position it just right, the SwitchBot can operate two switches at once. That’s right — one bot, two buttons.  In short, the SwitchBot is efficiency at its very best. 

A couple of caveats

If you’re like me, you’ll have to fight the urge to put a SwitchBot on every switch in your home or office. While I’m not opposed to making your life as easy as possible, there are some switches you shouldn’t automate.

Don’t attach a SwitchBot to a breaker or isolator switch. These aren’t things you should need to control remotely, and someone might use the isolator to cut the power to work on something. Being able to flip that type of switch remotely isn’t safe.

I did end up making some custom 3D-printed frames for a couple of switches because they had curved faces and I wanted a better fit (and I like using my 3D printers!). This approach was more something I wanted to do rather than something I needed to do to make it work.

Also: I stuck this power station in a freezer to test its subzero claims – here’s how it held up

If you want a robot to operate buttons and switches on a PC, the SwitchBot might not be your best option (because it’s one more ecosystem and yet another app to think about), and you might be better off with a different bot — the FingerBot

This device is part of a larger GL.iNet KVM (keyboard, video, and mouse) ecosystem and requires a Comet or Comet Pro remote KVM-over-Internet box to control it. This approach is a better solution to revive crashed PCs.

ZDNET’s buying advice

A SwitchBot is currently about $25 (down from $30 thanks to a 15% discount), and hubs start at about $35. The device is a great solution for those switches you can’t (or don’t want to) replace with a smart alternative for whatever reason (usually because you don’t want to open sockets or delve into the wiring). 

SwitchBot is also good for switches built into other things, like a coffee maker or a PC (hold that thought, I’ll get back to PCs shortly). I also like that all I need to move the SwitchBot is a new bit of 3M VHB tape, and I’m good to go.

Spotify aims to provide a consistent listening experience that uses minimal data. As a result, your audio quality might be less than ideal, especially if you’re using a pair of high-fidelity headphones or high-end speakers. Here’s how to fix that.

Switch audio streaming quality to Very High or Lossless

The default audio streaming quality in both the mobile and desktop Spotify apps is set to Automatic, which usually keeps the audio quality at Normal, which is only 96 Kbps. Even though Spotify uses the Ogg Vorbis codec, which is superior to MP3, OGG files exhibit slight (but noticeable) digital noise, poor bass detail, dull treble, and a narrow soundstage at 96 Kbps.

Even worse, Spotify is aggressive about adjusting the automatic bitrate. Even though 4G is more than fast enough to stream high-quality OGG files, even with a weak signal, Spotify may still drop the quality to Low, which has a bitrate of just 24 Kb/s. You will notice such a sharp drop in quality, even on a pair of bottom-of-the-barrel headphones.

To rectify this, open the Spotify app, tap your user image, open “Settings and privacy,” and tap the “Media Quality” menu. Once there, set Wi-Fi streaming quality and cellular streaming quality to “Very high” or “Lossless.”

I recommend setting cellular streaming quality to Very high and reserving Lossless for Wi-Fi, since lossless streaming is very data-intensive. One hour of streaming lossless files can take up to 1GB of data, as well as a good chunk of your phone’s storage, because Spotify caches files you’re frequently streaming. Besides, you’ll struggle to notice the difference unless you’re listening to music on a wired pair of high-end headphones or speakers; wireless connection just doesn’t have the bandwidth needed to convey the full fidelity of Spotify lossless audio.

You might opt for High quality if you have a capped data plan, but I recommend doing so only if you stream hours upon hours’ worth of music every single day over a cellular network. For instance, I burn through about 8 GB of data per month on average while streaming about two hours of very high-quality music over a cellular network each day.

How Audio Compression Works and Why It Can Affect Your Music Quality

Feeling the squeeze when listening to your favorite song?

Set audio download quality to Very high or Lossless

If you tend to download songs and albums for offline listening, you should also set the audio download quality to “Very high” or “Lossless.” This setting is located just under the audio streaming quality section.

The audio download quality menu in Spotify's mobile app.

If you’ve got enough free storage on your phone, opt for the latter, but if you’d rather save storage space, set it to Very high. You’ll hardly hear the difference, but lossless files are about five times larger than the 320 Kb/s OGG files Spotify offers at its Very high quality setting, and they can quickly fill up your phone’s storage.

Adjust video streaming quality at your discretion

The last section of the Media quality menu is Video streaming quality. This sets the quality of video podcasts and music videos available for certain songs. Since I care about neither, I set it to “Very high” on Wi-Fi and “Normal” on cellular, but you should tweak the two options at your discretion because songs sound notably better at higher video streaming quality levels.

If you often watch videos over cellular and have unlimited data, feel free to toggle video quality to very high.

Make sure Data Saver mode is disabled

Even if your audio quality is set to Very high or Lossless, Spotify will switch to low-quality streaming if the app’s Data saver mode is enabled. This option is located in the Data saving and offline menu. Open the menu, then set it to “Always off,” or choose “Automatic” to have Spotify’s Data Saver mode kick in alongside your phone’s Data Saver mode.

You can also enable volume normalization and play around with the built-in equalizer

Last but not least, there are two additional features you can play with to improve your listening experience. The first is volume normalization, which sets the same loudness for every track you’re listening to. This can be handy because different albums are mastered at different loudness levels, with newer music usually being louder.

Since I’m an album-oriented listener, I keep the option disabled. I can just play an album and set the audio volume accordingly, and I don’t really mind louder songs when listening to playlists, artists, or song radios.

But if you can’t stand one song being quiet and the next rattling the windows, visit the Playback menu, enable “Volume normalization,” and set it to “Quiet” or “Normal.” The “Loud” option can digitally compress files, and neither Spotify nor I recommend using it. This also happens with “Quiet” and “Normal,” since both adjust the decibel level of the master recording for each song, but the compression level is much lower and extremely hard to notice.

Before I end this, I should also mention that you can access the equalizer directly from the Spotify app, where you can fine-tune your music listening experience or pick one of the available equalizer presets. If your phone has a built-in equalizer, Spotify will open it; if it doesn’t, you can use Spotify’s. On my phone (a Samsung Galaxy S21 FE), I can only use One UI’s built-in equalizer.

To open the equalizer, open “Playback,” then hit the “Equalizer” button. Now you can equalize your audio to your heart’s content.


Adjusting just a few settings can have a drastic impact on your Spotify listening experience. If you aren’t satisfied with Spotify’s sound quality, make sure to adjust the audio before jumping ship. You should also check the sound quality settings from time to time, as Spotify can reset them during app updates.​​​​​​​
