A thermostat device returns JSON like data from the command line:
curl -s http://192.168.X.Y/tstat/humidity
{"humidity":51.00}
It would be interesting to setup a UNIX cron job to periodically script the upload of the data to a host so that it can be visualized (graphed). The command line device is an Asus router Configured with Merlin ASUS command set. A cron job executes a .sh UNIX script to save data to a USB memory stick.
The next step in the pedagogical exercise is to upload data to a cloud service and visualize data
QUESTIONS
What is the keyword search term that would quickly narrow down the IOT service providers that have an API that allows the router to upload data from a command line script (UNIX instructions)
If this is not possible, what are the leanest \ smallest options of API classes (Python MQTT etc). The better options have a small foot print because RAM is limited.
I realize that a router is not a raspberry pi, nor is it design for this purpose. That being said, I am speculating that the task to query and upload the result is well within its hardware capability.
