Hello @COLONEL92 

thank you for the case report.

The delayed reaction can have a lot to do with latency in the 2.4Ghz Wi-Fi network. Here are some suggestions:

-.here are some tips to optimize the network like try a different Wi-Fi channel width, update firmware of router

3. What to do if my local network is not stable

- you can try to create a Guest Wi-Fi network only for the smart devices to minimize wireless interference as much a possible

Try to use a Wifi analyzer app to select a Wifi channel that is less crowded

- To isolate the issue, you can connect one of the samrt plug to a mobile Hotspot Wi-Fi and see if the plug responds faster under a different network

Feel free to let us know if this works for you.
