Warranty does NOT cover if you brick your device during any type of update. Plugs will NEVER auto-update. All updates (even OTA) must be triggered by the user.

This plug is where it’s at. Safety first and then a plethora of functions/features to tinker with a link your printer up with your smart home, get notifications of power events, monitor power consumption and more!

I picked up a few of these as I have several 3D printers, two at work and one at home. Thermal runaway is something that always concerned me and this adds a strong layer of protection in this respect.
I run Octoprint on all three machines and the Tasmoto plugin is as the TH3D folks say, a seamless integration.
Setup was a breeze after watching the video in the support section.

I bricked my first one but that was on me, the device itself is true to its name. Its very simple to setup and it just works.

I now have these installed on all three of my 3D printers and can only say good things about them. I use OctoPrint to control the printers and the ability of the Tasmota plug-in to power off the printer in the even of a thermal runaway or other printer fault gives me more peace of mind. No need to sit next to it and babysit the printer.
I added a USB power isolator to eliminate any back feed from the Pi into the printer controller and this combined with the EZPlug allows complete remote control. On prints at home when I am at work, my wife just needs to power up the Pi and I can run it remotely. She then checks on it from time to time and occasionally gets to make fun of my rare failed print.

and it was easier to setup than the app-bound brands. I love that I can control it with a webpage and that its relay still works with alexa.
