Flash these switches with OpenSource Tasmota firmware to unlock the full potential of these switches. With Tasmota, there's no dependency on the cloud, no calls home, no privacy risk. You can use this switch as a standalone device by visiting the Tasmota website. In addition, Tasmota offers full MQTT integration on this switch for use with HomeAssistant or OpenHab. I have five of these switches with the Tasmota installed and they are bulletproof. The switch's remote control is great, but the real-time performance monitoring is amazing. I use these switches to control the current and power consumption of 3D printers. Plus, they're great for any devices you want to switch remotely.
