ToDo.txt

Add Alarm (i.e. send when temp above/below) possibly changing the sample rate as well

Add datalogging for when the network is unavailable - sent data latter when it is (may require an RTC for time stamps)

Deepsleep - data may be able to be retained by saving the RTC memory (machine.RTC.memory())
~~~
import machine
import ujson
rtc = machine.RTC()
d = {1:'one', 2:'two'} # Example data to save
rtc.memory(ujson.dumps(d))  # Save in RTC RAM

r = ujson.loads(rtc.memory())  # Restore from RTC RAM
# r == {2: 'two', 1: 'one'}
~~~

std watchdog timout is 8secs - so we need to either make sure that we can update the timer or create a second timer

add SSL
add Firmware update OTA
change credentials from mimos
