@yawns my sensors will upload the sensor values to thingspeak.com. do you know how I can get the values from the thingspeak.com and make a graph out of it on the magic mirror ?

@sdetweil thats Great, but how do I use the api? With magic mirror
-
@sdetweil i have an arduino device collecting samples from a water well system (2 flow sensors and 1 volume sensor)… I use Blynk to post the data to a cloud server, and then I use their data api to retrieve the data and a charting tool to present 2 sensors of data on MM.
i wrote my own module
i also use the blynk mobile app to display the data in near realtime…
-
@icripps api definition says data can be returned in json format… and you might be able to use the MMM-Chart module
