First, Thank you for all your hard work in porting so much of the Arduino functionality in to such a low cost hardware device !
I would like to use the ESP8266 to monitor temperature, humidity, light level, and motion detection. I will be using about 50 units to capture this data from sensors every 10 minutes or so, but would only need to upload this data via Wifi every 4 hours or so.
I read elsewhere on your Basic forum that following the completion of a SLEEP instruction, the ESP8266 will require about 30 seconds before execution of the default program begins. I have also read of a recent 5x speed up in general basic code execution.
Questions:
1) Is is STILL true that about 30 seconds is required before the default program begins executing following a SLEEP instruction expiration ? Perhaps the speed up of code has improved the start up time ?
2) How low can the power consumption be reduced during this 30 seconds ? I'm concerned that 0.5 minute ON, then 9 minutes+30 seconds OFF, which only reduces power consumption to 5% of the continuous-operation mode will still drain the batteries much too fast.
3) Are there any 'tricks' or 'work-arounds' that might vastly improve power consumption when only very infrequent WiFi use and data acquisition is required ?
Thanks,
Greg
