Setting Up a Radio System from Scratch
Is it necessary to periodically transmit? What are downsides to only transmitting on state change?

There's no way to know that the payload has been received - they're transmitters, not transceivers. The messages are idempotent anyway, so just retransmitting makes the whole system simpler.

Losing the state change in the noise. The receiver is the more interesting end in a setup like this.
