Somebody asked me if the Sideclick Remote Attachment was compatible with the new 2020 Fire TV Edition remotes that are now included with Toshiba and Insignia Fire TV Edition televisions, as well as TCL and Nebula Fire TV Edition soundbars. Sure enough, the Sideclick fits perfectly. That was no surprise, since, unlike the old remote which is thicker, the newer Fire TV Edition remote is the exact same width, thickness, and shape as the Alexa Voice Remote which comes with Fire TV Sticks and Cubes.
For those of you not familiar with the Sideclick Remote Attachment, it is a column of programable IR buttons that clips onto a Fire TV remote. Even though the Sideclick’s buttons are marked with power/volume/channel/etc.. icons, the buttons can be programmed to replicate any button on an IR remote that you have by simply pointing the two remotes at each other. You can find my review of the Sideclick here. Since a Fire TV Edition television remote already has all the TV control buttons you would need, the Sideclick would be best used to control other devices in this use case, such as A/V receivers, cable/satellite boxes, and Blu-ray players.
In summary, the Sideclick Remote Attachment is compatible with all Fire TV, Fire TV Stick, Fire TV Cube, and Fire TV Edition remotes EXCEPT the 2017 Element/Westinghouse Fire TV Edition remotes and the 2018/2019 Toshiba/Insignia Fire TV Edition remotes. The new 2020 Fire TV Edition remote is backwarsd compatible with 2018/2019 Toshiba and Insignia Fire TV Edition televisions, so if you want to use the Sideclick with those TV’s, you’ll need to buy the new remote. There is no way to use the Sideclick with the 2017 Element and Westinghouse remotes unless you make your own attachment mechanism.
