The Logitech POP is an exceptional addition to the smart home. The POP is a programmable button that you can configure to do a number of useful things in any smart home. They have a removable adhesive that you can attach to a wall or table.
I was so excited to get the POP based on what I read it could do. We have a full array of Sonos devices in our house as well as August locks and Lutron Caseta lights. We also use the excellent Logitech Harmony Hubs for our remote controls.
I purchased a starter kit and 2 additional pops.
Here is how I am using them.
Kitchen - POP button 1:
Play/Pause Sonos with Apple Music
Play/Pause Sonos with Spotify Top Hits
Play/Pause Sonos with NPR
Kitchen - POP button 2:
Turn off Sonos, and Turn on TV
Unused
Turn off TV
Bedroom - POP button:
Play/Pause Sonos with NPR
Play/Pause Sonos with Spotify Top Hits
Turn off Sonos and Bedroom Lights
Setup
Super easy. Plug in hub, set up app, and add POP devices.
In the app you discover all your local devices (Sonos) and then cloud authorize Harmony, Lutron and August.
Each POP comes with that cool double sticky stuff that is removable and re-usable.
Programming
You just drags and drop, chose options for each device (such as toggle or on/off) and you can also add multiple devices per command
Each button has 3 commands (single click, double click, long press)
Shortcomings
Sonos
You cannot group speakers together. No sonos interface can do this except Sonos for some reason. Also, if you make changes to your Sonos playlists (which is how you select items to play) it doesn't seem to refresh without re-discovering.
You can't easily control volume.
You can't skip songs.
Harmony
If you have two Harmony hubs in your house (for 2 TVs) you have to pick one to use. You cannot seemingly pair two different buttons to different Hubs. It's one hub per account.
