A UK smart plug that arrives already running Tasmota. No app, no account, no cloud service that can be switched off. It talks MQTT to your own Home Assistant and nothing leaves the building. What it's for The cheapest honest way into local home automation. Plug it in, point it at your MQTT broker, and you have switching plus real energy monitoring on anything portable — a dehumidifier, a 3D printer, the tumble dryer you'd like to run when the solar is producing. Why pre-flashed matters Flashing Tasmota yourself means opening the case and soldering to test points. We ship it done. If you've never used MQTT before, this is the twenty-minute introduction — one plug and a Home Assistant install teaches you more than any amount of reading. What it works with Home Assistant over MQTT — auto-discovery works out of the box Node-RED, openHAB, or anything else that speaks MQTT Tasmota's own web UI for setup — no phone app needed Notes Energy monitoring is the useful bit. Power, voltage, current and cumulative kWh all report to Home Assistant — which is what makes solar self-consumption automations possible. For anything permanently wired, use a relay board instead.
