I have Xiaomi Miflora sensors on my garden. It was impossible to connect them through my bluetooth USB stick. Thanks to the Theengs bridge, I see all of them and can create automations in Home Assistant.

Works well and has a good range, you do need to have a reasonable level of technical prowess it’s not quite plug & play, yet…. The price was so attractive it was not worth the time and effort to build my own as I may have done in the past.

Great little device that opens up the ability to add devices to HA

My SmartHome is pretty well bristling with devices. There's one of me, three cats and 92 current DHCP leases. This wasn't my first MQTT rodeo. So long as you have your wifi network name, your MQTT username and the passwords to both setup is pretty fast.

It wants uppercase letters in the hexadecimal password by the by.

Overall, this device is an excellent addition to my Home Assistant setup.

First impressions: It’s a solid piece of hardware—sturdy, satisfying to hold, and clearly well-built. Setting it up was a breeze; I had it connected to my Wi-Fi in just a few minutes. I also enabled the Home Assistant add-on by mihsu81, which immediately started displaying plug data. A standout moment was seeing the BLE-to-MQTT gateway in action—it automatically detected a nearby CO2 sensor and seamlessly added it to my dashboard. Truly impressive.

Florian is very responsive to emails and answers questions quickly - he helped me connect to my MQTT server securely. The forum is also an invaluable resource for community-driven support.

One thing to note: the software ecosystem for this device isn’t centralized under a single GitHub organization. This means you may need to spend some time tracking down the right tools to use.

Update:

After working with Florian and applying a couple firmware updates everything is working as I had hoped it would. The boot looping has been corrected and the device is very stable now. The Blind Tilts are seen and with the latest dev branch the ability to control them works.

I wanted to update my review to show the fast progress and response, and I want to leave the original text to show the context of the changes. It's not often small shops selling niche products like this are able to respond to issues as I've experienced here and I hope others interested in this product see this and will see that if they do have issues, at least a genuine attempt to correct them will be made if not a full solution provided.

Original rating was 2 stars, this was my text:

I intended to keep trying to find a way to make this work, but it's not working as I'd hoped.

Biggest problem is it works for a couple hours then goes into some sort of boot loop. I've reset a couple times, just let it sit, and it dies.

Even when it is working, it's not seeing my SwitchBot Blind Tilts, which was the whole point for me.

Like I said, I intend to keep trying to get this work at some level but have low expectations.

Also, the box has a QR code and a written out link for the manual. It's wrong.

I needed a smart plug to add to Home Assistant, and I also wanted to extend my Home Assistant’s Bluetooth range. This does both very well. Has every function you’d expect from a smart plug, and Bluetooth devices get added to MQTT easily. Integration and adding this to home assistant was quick and easy. Highly recommended.

Used plug to monitor sharp dips in voltage when running on generators during a power cut. Added a switch to disable the economy setting all integrated into Home Assistant. Worked with a developer who tested my scenario and gave me a custom file. Thank you!!

I received two Smart Plugs with the intention of using MQTT to trigger them on or off (no added functions needed or tested). The product works great! The only issue was MY understanding of the Broker Setup, but Florian was WONDERFUL in walking me through steps (till I eventually found my own dumb typo) and now they work perfectly! Will be buying more for future projects!

I needed a bluetooth bridge for Home Assistant which I could place closer to the car than my HA server. This device worked like a charm.

The only thing I wish is that it had PoE so that I could run just one cable to the device. (you can have just one cable, but that would be USB-C as power supply and then use WiFi instead of the Ethernet port, but I like cable Ethernet for its reliability)

I have two smart plugs working away in my greenhouse automation. Great product with Home Assistant.

I integrated this with Node-Red without too many issues. When I did have a question, Florian was more than responsive. Don’t hesitate - buy one.

With seamless integration with Home Assistant through MQTT this plug make it a breeze to connect my bluetooth sensors (temp/humidity) in my charcuterie drying room and automate a dehumidifier device to maintain optimal conditions for your curing process.

This plug offers efficient connectivity with BLE message analysis, making it incredibly easy to transform any ordinary device into a smart one.

This Theengs PlUG is must-have for anyone looking to elevate its home automation game while keeping away the burden of handling the ESP32/BLE message parsing.

I already used the Theengs APP before getting the Theengs PLUG, and these are both good software/tools with good customer support.

I do recommend!

(because the plug also provides electrical consumption, I start using the energy dashboard in HA. This opens new project with this theengsplug!)
