Issue with Meross MSS210 plugs
<!-- You must use the issue template below when submitting a support request -->

**Describe Your Problem:**
I have connected four Meross MSS210 plugs to the Meross app on iOS. I have sniffed the sign, timestamp and message ID using HTTP Catcher, and input the values. However, I get the following error in the log, and the switch is unresponsive.
