Issues

Partial block size pdata fails NIST test vector

RC5 Stack Overflow Fixes

Move Messaging.cpp into libs

Write scratch space verison of decode routines

Make enc/decodeSecureFrame function calls less confusing

Preprocessor switch before defines passed in.

mistake in Messaging.cpp docs

JSON stats cannot be disabled in SystemStatsLine

Create versions of motor drivers that only track travel in one direction

5s false occupancy reported at least 10am to ~5pm 20170322

Test OTSIM900Link.basicsDeadCard never completes on RPi

Shaft encoder diode too bright.

Create C++ unit-test-friendly thermal model framework and initial tests

Move more of valve start-up / wait-for-fitting logic into CSD logic

Urgent tasks

Look at candidiate SHT21 replacements

Reduce valve travel, eg not always 200% RT for single burst of heating

Break out SHT21 RH%/temp calcs and unit test against example in datasheet

Ensure that pot (or replacement) meets design life

Avoid valve hovering above 50% indefinitely (when not actually open), forcing boiler to run pointlessly

Move sideview LED away from top edge.

Enlarge motor encoder pin holes

Enlarge potentiometer pin holes

Suppress (rapid) warm-up when light briefly on in middle of night
