Let's Control It

I may be missing something but what can I do to continuously read an analog (knock) sensor and (using a limiting rule) publish the values? If I set the time interval to 0 it resets to 60.

Minimum interval for continues reading is 1 (second). Only input devices is set to 0.

Thanks. This confirms my observation, I'll stop my search and stick to my Arduino sketch to continuously read analog values then.
