What is proper presentation type for binary push button? S_BINARY ? And how make controller distinguish between binary button (RO) and binary switch (RW)?

[matkor]

Assuming I have light switch/push button with only readable state (via pin on Arduino).
Following https://www.mysensors.org/download/serial_api_20#sensor-types ,should I present it via:

present(CHILD_ID, S_BINARY);

?

Later, having binary switch (which should be settable from controller) how it should be presented?

How controller can distinguish between RO button and RW switch?

@matkor it is currently not possible. https://github.com/mysensors/MySensors/issues/1312 suggests a solution but there has been no forward progress lately.
