I am looking at ThingSpeak for logging sensor data.
I would like to log three different variables at a frequency up one datapoint per second. This would be 86400 samples per day or 259200 values per day.
The thingspeak "pricing" page says that on free accounts:
- "The number of messages" is limites to ~ 8200 per day.
- "The message update interval" is limited to >15 seconds.
My question is: for ThingSpeak, what counts as a "message"? Is it each http request or each sample?
I.e. can I collect my samples for, say 120 seconds, and post them as a bulk update? This would be only 720 http requests per day but still 86400 samples per day. Would this fit into the ThingSpeak limits?
