Describe the issue

Since about two weeks the devices don't receive commands anymore. They are correctly connected with WiFi, correctly connected via MQTT and I can see them in HA without any problems. But when I send a command in HA (switch on f.e.) ... nothing happens. The switch in HA move to "ON" and after a few moments back to "OFF". In the other direction it seems to work. If I turn on a device via Govee-App, their state will change and shown in in HA correctly.
Two weeks ago all worked fine, it's a new problem.
