[Feature Request] Ignore states not in mapped dict #51
Description
First of all, thanks for the Integration. This replaced most of my nodered flows.
The only problem I have right now is that all states of the event are used.
I use the Integration with some 433mhz PIR sensors which are sent to HA via the esphome.rf_code_received event.
The events received all have the same device_id (same rf bridge).
I already mapped the event codes, but there are also other rf codes shown as state.
Could you please add a checkbox to ignore those?
I already looked into the code, but integrations seem to be a bit more complicated than cards.
