I've been dealing with the persistent failure of my old 433 MHz remote-controlled plugs. The issue likely stems from their inadequate capacitor power supplies, combined with my home voltage consistently exceeding their design specifications. Living near a transformer station means I can experience voltages up to 242 VAC. It's clear that an upgrade is necessary.

I’ve decided to switch to TASMOTA-compatible smart plugs from Amazon. Most of these plugs are built on the ESP32 platform with TASMOTA firmware, allowing seamless connection through MQTT.

After conducting some data probing, I successfully developed a flow in Node-RED. (Next time, I’ll be sure to consult the documentation first: https://tasmota.github.io/docs/MQTT.)

Additionally, coding this in Codesys-PLC is a feasible option as well.
