**With this modification it already updates the app status of the 3 plugs.**

After several tests, this is what I see that it does not work well or as expected:

- This strip has a button that activates or deactivates all 3 plugs at the same time. When you press it, **app only updates the state of the main socket (1)**.  
I am not able to capture these events from switch 2 and 3, only the event received from main is seen in the log.

- The same happens with the configuration reports, they should send status every 300 sec and only the main component sends it.

- If you send a “refresh” command, update the 3 plugs.

- **A solution that works is to program a timer every 300 sec that a refrech executes.**

- **Automations are local if you only execute actions on the “main” socket.** If you perform actions with plug 2 or 3, they are not local.

- What I already commented in another post, in automation it does not show the names of the plugs. Shows all actions followed. This also happens now with multi button DTHs.

- The timer controls are not independent for each socket. They work at the same time on all 3 sockets.  

- Quick control only can programmed and executed for one plug (switch 3).  

- The programmed quick control appears with the name and the action. With DTHs only the action appears.  

- The Event History does not differentiate which plug is the event.  

- In the app you cannot change the name of the plugs, you can only change the name of the strip, which appears in the tile and corresponds to the main.

Thanks
