@skywatch I guess the color will work only with "A sensor graph", Not for grouped and mixed. In these graphs colors will be chosen randomly(we may have more than one same type variable in these graphs).
@skywatch thanks for the feedback. Option #1 will be good.
unfortunately, we cannot support Option #2, whole system backup. We can run MyController on many platforms(Linux, Windows, Mac, etc.,), it is very difficult to maintain the backup code.
@ragflyer I have fixed @cimba007 solution. yet to fix it fully.
Your log says something like your trying on the corrupted database. can you copy the running database and try again. Kindly do a backup before any actions.
I will try to publish json API. We can use it anywhere.
@tag I briefly considered caching data at the node level, but memory limits of the arduino modules and/or the added cost & complexity of having SD Card/FLASH modules at every node seems like a big hurdle.
But...caching at the gateway or repeater might work out a little better.
If your DHT11 returns "nan" it means that it is not possible for the node to read the sensor, or received undeadable data, so the result should not even be send to mycontroller. You could try to make your sensor aware of this reading by using the isnan() function...
