hey,
Can anyone help me out? I have build Andreas his project with 4 buttons and 4 leds.

Attached version of Reminder_Analog has the following improvements:

• Uses new version 2.0 of Sujay Phadke's HTTPSRedirect

https://github.com/electronicsguy/ESP8266/tree/master/HTTPSRedirect

• Introduces new task status to the state machine: Pending

(when user presses a button to create a new task, but before the task has been created in GCal).

This new status makes the code simpler in manageStatus().

• Records the status in permanent memory, so the device can be switched off temporarily and it will remember whether the task has been completed.

• User-defined constant to configure delay before writing to permanent memory

This is useful to save writing unnecessarily, for example in the common situation where someone presses a button to activate a task, then immediately presses again to cancel (either when demonstrating the device, or to correct a mistake).

Without the delay will result in 2 (wasted) write-cycles, whereas with the delay there will be no write at all.

• Copes with situation where a button is pressed again while GCal event is still active.

(previous version did not respond in this situation).

• Monitors heap memory

(useful to illustrate leaking memory problem with v2.4.1 of the ESP8266 library)

• Heartbeat routine only flashes the currently-active LEDs instead of all of them.

(distracting otherwise when no tasks are currently due).

• Heartbeat also flashes the Wemos internal LED

(I don't use D4 for that reason).

• User-defined constant to configure the Hearbeat frequency (set to zero to disable Hearbeat altogether)

• User-defined constant to configure the frequency of status printing.

Future enhancement:

It would be nice to do away with the current polling solution using a Ticker object.
Is it possible to use a proper hardware interrupt to signal when to read the analog pin (A0) - e.g. by connecting the switches to another input pin as well as A0?

At the moment, if someone presses a button while the calendar is being accessed, there can be a delay before the LED status changes, and the key press is occasionally not registered at all.

Now esp cannot access to calendar data because this document moved temporality. How to fix this issue? , Thank you.

Moved Temporarily

END OF RESPONSE

There seems to be a problem with the persistence of still active (but expired events in Gcal) events. On startup it starts fresh, re-reads what is available in the Calendar and sets the led accordingly. However as the event is now due in Calendar, it is not seen, even though it has /not/ been acknowledged. Oops. one power failure and the missus is mad at you again :P

It would be advisable to store the active, unacked state in eeprom as well, so that at startup we still know we had an un-acked event.

This is the error i'm getting when the code is run in doGet:
6:28:47 PM
Notice
Execution started
6:28:47 PM
Error
TypeError: Cannot read property 'parameter' of undefined
doGet
@

I have no idea what i'm doing wrong.

I used the code from the file:
function doGet(eve){
var title = eve.parameter.title;
Logger.log(eve);
//Logger.log(ContentService.createTextOutput(CreateEvent()));
return ContentService.createTextOutput(CreateEvent(title));
}

// Replace XXX with your calendar name
function CreateEvent(eve){
var _calendarName = 'Aufgaben_Familie'
var MILLIS_PER_HOUR = 1000 * 60 * 15 ;
var now = new Date();
var from = new Date(now.getTime()-60000);
var to = new Date(now.getTime() + 1 * MILLIS_PER_HOUR);
var vCalendar = CalendarApp.getCalendarsByName(_calendarName)[0];
vCalendar.createEvent(eve,
from,
to)
// Logger.log(currentTime);
// Logger.log(vStartDateValue);
// Logger.log(from);
// Logger.log(to);
// Logger.log(vEndDateValue);
return true;
}

I got this:
