What is this little white box?

This little box is a Wifi outlet that gives you control over your printer power (or any other 110V device power if you want). The difference between ours and others is that we’re running Open Source firmware (Tasmota) on these. That means no sketchy apps to install on your phone or accounts to sign up for to get it setup. Unlike other plugs that require complicated flashing and/or soldering to liberate from the “cloud”, these come pre-flashed with Tasmota on them.These plugs are 100% locally controlled so you can rest easy knowing that only you have access to it. These work with the Octoprint Tasmota plugin, Klipper Tasmota Support, and home automation platforms like Home Assistant. All our source code is available so you can be sure what is on your network. We believe that this is your device so we have NO remote access or control over them.When you combine this plug with your Octoprint installation it gives you powerful control of the printer right from your Octoprint web interface AND extra safety in the event of an issue with the printer. You can have this plug shut off your printer if there is an issue with the heaters or if the printer goes into an unresponsive state. Both versions of the plugs support on/off commands and the EZPlug+ bakes in power monitoring for you data nerds out there.

Firmware Updates

The EZPlug firmware can be found on our EZHome releases page here: Releases · th3dstudio/EZHome

Using the EZPlug with Standard Tasmota – ADVANCED USERS ONLY

Our plug is compatible with regular Tasmota when set up with the correct template. The EZPlug+ will need to be calibrated per the Tasmota guides.You are welcome to use standard Tasmota with your EZPlug but this is not covered under technical support. Only when using the EZPlug with our firmware is covered under the support coverage. This is because we pre-setup and calibrate values for the plugs to make sure things work correctly out of the box, when using standard Tasmota all these custom settings are lost. Converting to the standard Tasmota firmware is for advanced users who have experience with Tasmota.

Powering the Raspberry Pi Note

To use this plug with OctoPrint you must be powering your Rasbperry Pi from a power source that is NOT your printer power supply. We have AC adapters here for Pi4 Boards in our store here: Raspberry Pi 4 – 3 Amp Power Adapter with Switch – USB C

    Bought one of these plugs and was having some trouble getting it connected to my wifi. I had followed all the steps in the documentation and was sure to connect to a 2.4GHz network instead of 5. I ended up opening a ticket, got a response back within an hour or two and was asked to reset the plug. However, before resetting the plug I simply moved it to a different position in the room. It connected right up, so the problem was on my end.

    Still, pretty good customer service, and once the device connected, I was able to set it up with OctoPrint.

    EDIT: I’ve tried to get Arthur to return the plugs so we can replace them but he refuses to cooperate. I cannot help people who just want to complain and not actually get things resolved.

    I hope this message finds you well. We kindly request that you send these plugs back to us for a thorough evaluation. Once we receive them, we’ll promptly send out replacements. Our team will also disassemble the plugs to identify the root causes of the issues you’ve encountered.

    Additionally, it would be immensely helpful if you could share information about the printers these plugs were used with and the specific environmental conditions they were subjected to. This will aid us in further improving our products.

    Your satisfaction is important to us, and we appreciate your patience and assistance in this matter. If you have any questions or need further assistance, please don’t hesitate to reach out. Thank you for choosing our products! I will send our RMA approval over to you in just a minute that will have the address where to send them back to us for replacement.

    Easy to setup, use, and get working with HA. All of my printers have these since they are not only able to be turned on and off via my phone, but I also keep track of electricity useage.

    This is a must addon for your printer(s).

    I purchased this smart plug to control my Ender 5 printer using OctoPrint, but quickly found out it was useful for my other home automation needs. Since I have a Hubitat home automation hub, I installed the Tasmota driver using the Hubitat Package Manager and then configured the smart plug manually. Now I can control the plug using my Hubitat routines. Next I ticked the device in the Amazon Echo Skill app in Hubitat. Now I can control the smart plug using Alexa too.

    I purchased the EZPlug over 6 months ago. I don’t even have to think about, this product simply works. every time I send a job to the printer, it turns on. After a print finishes, it shuts down 10 minutes after. With the Tasmota Plugin in Octoprint, I can set automatic power up/down, add a second independent layer of thermal run away protection, and still directly log in to the EZPlug and toggle power from there as well. Octoprint also has a color coded graph that displays the power consumption, amperage, wattage, and cost per kilo watt over time. Setup was a breeze, I just connected to the plugs own wifi. Put in my wifi”s info and that was it.

    I’d had many problems with the integration of other products with Home Assistant. This was related to over the air updates that apparently interfered with initialization when Home Assistant reboots with firewall enabled (similar to TP-Link HS-100 HS105). However, with the EZPlug there’s no app to download and no possibility of phoning home to download updates without permission. Using the EZPlug to control two lamps at sunrise/sunset with no problems so far. Requires Home Assistant and MQTT with port 1883 open on server.

    I was part of the public beta team
    and using it for a while now in HA the setup was 5 Min and the upgrade to Tasmota was 5 more Min no issues so far i test it under high load (1500W Heater and washer machine) no issues at all
    power reporting was on point

    Great for octoprint and super easy to set up. Set up video is easy to follow and made setup a breeze. Added so much functionality to octoprint. My favorite is the off with gcode, I have it in my end gcode and set the delay for 5 minutes. That gives the hotend the right amount of time to cool off and then the printer turns off. I also got this to work with fluidd but the integration isn’t as nice as octoprint.

    Got the EZPlug+ to power my Ender 3 with. Works fantastically. Easy to set up. Love the fact that the plug has a button on the side so you can still manually turn it on and print without going through octoprint if you wish.

    I bought several of these for my 3D Printers and the set-up was relatively quick and easy. Recommend following Tim’s video and you should be good to go. I like that I have extra added protection in case there is an issue with the printer. Extra peace of mind.

    I received the standard and plus versions as part of the beta team. They are very simple units, with a big capacity.. Setup took all of 2 minutes to get it on my wifi, and about another 2-3 minutes setting up the Tasmota OctoPrint plugin. Software is based off Tasmota, and can easily be upgraded to vanilla tasmota using the provided template. The power monitoring is awesome, and I love that you don’t have to calibrate the unit like other plugs out there. Tim and the Th3D team have knocked it out of the park with this product, yet again.

    Have been using both versions for a while now. Love that everything can be handled locally without the need for the cloud. The power monitoring version works great too, nice way to track usage. Got it working easily with Octoprint Tasmota plugin, and now I never have to mess with turning my printer on and off anymore. Love it!

    I received a beta unit of the standard ezplug for testing. I had the plug working and connected with octoprint using the tasmota plug-in in 5 minutes without the instructions even being written for the unit. It works and requires no opening and flashing of the plug, and does not send any info out across the internet.
