sendNotification help

I want to be able to send a value to https://github.com/mykle1/MMM-EventHorizon to change the time used in a count down timer. Right now I can make the module hide with…

this.sendNotification('HIDE_TIMER');

but I cant seem to do much more, how do I change my sendNotification to include a payload to change the date and time in MMM-EventHorizon. I will have to change the notificationReceived in MMM-EventHorizon to I assume…

@jasondreher just add the payload on to the api call like this

this.sendNotification('HIDE_TIMER', payload);

‘payload’ can be anything… a variable (this.variable_name), a literal(‘some literal string’), a dynamically constructed value (‘some value’ + variable_name + ’ right now ')

the receiving modules sendNotificationReceived(code, payload, sender) function is responsible for ignoring or processing the payload data according to the shared rules of the sender

OK so I change my sendNotification to

this.sendNotification('SHOW_TIMER','18:25:25');

and the MMM-EventHorizon notificationReceived to

    notificationReceived: function(notification, payload) {
        if (notification === 'HIDE_TIMER') {
            this.hide(1000);
        } else if (notification === 'SHOW_TIMER') {
            this.show(1000);
            this.time = payload //I added this
            this.updateDom();  //I added this
        }

    },

Thinking the paylaod will update the countdown time but it does nothing… Not sure what I am doing worng. I have tested this quite a few different ways and searched quite a bit…

I can tell its doing something as it flickers (like it is refreshing with the updateDom) but the countdown does not reflect the new time.

@jasondreher you didn’t use the payload. Just hide and show. I don’t know the other module.

But I would guess u need to start a timer with some elapsed time til the action (from now)

@jasondreher said in sendNotification help:

this.time = payload

I added “this.time = payload”, this is using the payload correct?

@jasondreher said in sendNotification help:

this.time = payload

probably

this.config.time = payload
