Once motion is detected, there is a transmission holdoff timer for 60 seconds
before it goes to no motion mode (light flashes once, no transmission)

NO MOTION: (60 second timeout from motion)

KNOCK ON TODOs
- need to pass forward radio config parameters to get INNER_TIMES=75 for the MiHome Light.
  - need to think about config.tx_repeats vs get_config() - these are different concepts

- code up product id's
- code up paramid's for decoding messages
- decide how to handle low battery alarm, this is the first alarm we have seen.
