MMM GoogleTask implementation - MMRIZE/MMM-CalendarExt3 GitHub Wiki

This cannot be done by the CX3 module itself; you need MMM-ModuleMonkeyPatch.

{
	module: "MMM-ModuleMonkeyPatch",
	config: {
		patches: [
			{
				module: "MMM-GoogleTasks",
				method: "socketNotificationReceived",
				patch: function (original, args) {
					const [notification, payload] = args
					const ret = original(notification, payload)
					const tasks = this.tasks || []
					const items = tasks.map((item) => {
						const symbolMap = {
							'needsAction': 'circle',
							'completed': 'check',
							'canceled': 'times',
						}
						const startDate = (item?.due) ? new Date(item.due) : new Date()
						return {
							title: item.title,
							startDate: startDate.valueOf(),
							endDate: (item?.completed) ? new Date(item.completed) : new Date(startDate.valueOf()),
							description: item.notes,
							location: item.selfLink,
							symbol: [ symbolMap[item.status] ],
							calendarName: 'GoogleTasks',
							color: 'red',
							fullDayEvent: true
						}
					})
					this.sendNotification('CALENDAR_EVENTS', items)
					return ret
				}
			}
		]
	}
}

But, MMM-GoogleTasks lost the time information of due, so I can not revive the exact due time. MMM-GoogleTasks is missing the details of events. (e.g. fullday event or not, due time, ...) So this patching is limited.
