Need help with configuration

[ferbulous]

Hi, I have wall switch (bthome receiver) with 3 light bulbs (bthome transmitter)
Is there an example on how I could have the bthome receiver transmit button clicks to toggle all the lights for the nodes?
If I'm describing the roles correctly.
Or would I need another esp as bthome receiver and the rest configured as transmitter?

Since there's an issue using esp32 as receiver, what's the maximum nodes for a receiver on esp8266?
