Simple install/maintenance with UI LEDS/pushbutton

[neilh10]

When installing a Mayfly/ModularSensors or making a maintenance visit to a geographical site, it would be good to have easy visibility on the locations status.

There are 2 LEDs - a red and green, and two potential push buttons for status requests.

For an installer, the stages of installation are likely to be

• Physical install and power up
• Sensors communicating
• Wireless communications successful

For a maintenance visitor they are likely to require

• Active feedback of working system
• For problems, current power issue, either sensor issue, wireless issue,
• The User button could be used to ask for non-intrusive status
• The Reset button could be used to validate system operation as per the installation process.

The maintenance visitor is likely to only have limited capability

• apply power (external battery)
• check sensor cables and connections
• possibly check wireless connections Mayfly to internent, but this can be difficult.
• field replaceable Mayfly
• if they bring a computer, they can potentially update the Mayfly software - but currently there is no capability to read Mayfly status

As of Mayfly 1.1 there are also other LEDs
the Switched Power Out applied RED led
Network Bee Status - blue - SJ17 soldered
Bee Power - white - SJ16 soldered

The UI status on TWO LEDS could be something like this .. but needs to be simple, and checked with a real users to see how it flows.

• Power up - Green Red flash - GrnOn/0.25 RedOn0.25sec - 4 times. As of 0.33.0 does this
• (Time good, successful sync - all part of data anylsys)
• Time Sync needed/fail? - 2 Red flashes RedOn/1sec OFF/1sec pause15secs
• Reading sensors Start - Green fast flash (0.25secon on /off) - at least two green flashes, but longer if sensor sampling takes longer
  Bee Power LED (if enabled)
• Modem Looking for signal - solid blue (Digi S6 and CAT-M1)
• Modem Connecting - flashing blue (Digi S6 and CAT-M1)
• Modem Connected and passing data - solid blue.
• Good handshake MMW 201- data delivery - Green led on solid for at least two seconds
• Failed to deliver data -Red led on for at least two seconds

For sensor priority in failure as follows

• SD card Fail (not inserted) - 1red1grn flashes - RedOn1sec Off1sec GrnOn1sec pauseOff/5sec

• Sensor Fail - 2 fast red Flashes RedOn/1sec OFF/1secs pause 15secs/OFF

• WakeUp ack - 2 Grn flashes, Grn/1sec off/1sec (typically on UserButton push)

• For power savings after 30minutes, no LEDs flash in closed box.

• Sensor button short push initiates leds Wakeup (less than 2secs)

• Sensor button long push initiates sampling. (greater than 2secs with Grn leds flash)

• Sensor button push after initial start up - initaites reading.

TO implement this need to be able to have a FSM for SysStatus
This needs to have a timer event into it to support flashing LEDs.
This probably lives in the already massive Class Logger

so probably need to be initialised with RedLED, GreenLED
SysStatusEvt - the above events are mapped to inputs.
SysStatusTimerEvt - called every 200mS
