Easy to install - and great support

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.

This Theengs ESP32-driven electrical plug is a game-changer for DIY IoT projects!

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!)
