Switching one Tasmota device triggers all devices

So I configured MQTT and auto discovery (SetOption19 1) for my plug sockets (4x Gosund SP1). They are all discovered inside HA and show up with their respective (different) names.
The problem is as soon as I switch one of them all others switch too…
Any ideas what the cause for this is?
Please let me know if more information is needed.
(btw. first time HA install :slight_smile: )

Check your mqtt topic names. They should all be different.

Perfect, thanks for the quick solution.
