You're super-quick!!!

I updated the version, and now the issue is fixed.
For the time being everything is running fine, I'll let it run for a pair of days and let you know if I find any issue.

By the way, I suggest adding something in this page to expose the ack flag status:

@skywatch source and value looks very good to me!

Works perfectly!
You rock!

@jkandasa Actually without going in edit you don't have anything telling you if this GW uses ack. Enabled / disabled would be enough for me.

@jkandasa Maybe I misunderstood the meaning of this class, but what about "message" instead of "field"?

I can confirm that with 23 hours the scheduler works perfectly now!
Thanks a lot!

Done! 494

Now that's clear, I'll try using 23 hours.
Thanks!

@jkandasa I managed to get the result using a slightly different approach. I saved previous node state in a repository variable, then looped over the nodes list and compared actual state with previous one, sending en email only when state changes.

I'm not a java programmer, so any suggestion on the code is more than welcome:

var myImports = new JavaImporter(java.io, java.lang, java.util,java.lang.Object, org.mycontroller.standalone.utils.McUtils);

with(myImports) {
	var options = new HashMap();
	options.put("orderBy", "Eui");
	options.put("order", "asc");
	options.put("pageLimit", new Long(-1)); // -1 to list all the nodes

	var nodes = mcApi.node().getAll(options);

	var nodesVar = mcApi.variable().get("Nodes state");
	var nodesOU = JSON.parse(nodesVar.value);
	var nodesOD = JSON.parse(nodesVar.value2);

	var nodesU = [];
	var nodesD = [];

	var subject = "[MyController] Nodes status";
	var messageU2D = "";
	var messageD2U = "";
	var message = "";

	for (i = 0; i < nodes.data.length; i++) {

		var nodeStatus = new Object();
		nodeStatus['key']   = nodes.data[i].getGatewayTable().getId() + '-' + nodes.data[i].getEui();
		nodeStatus['state'] = nodes.data[i].getState();

		if (nodeStatus['state'] == "UP") {
			nodesU.push(nodeStatus['key']);
			var prevState = "";
			for (j = 0; j < nodesOU.length; j++){
				if (nodesOU[j] == nodeStatus['key']) prevState = "UP";
			}
			if (prevState != "UP")
				messageD2U += nodes.data[i].getEui() + " : " + nodes.data[i].getName() + " : " + mcApi.utils().friendlyTime(nodes.data[i].getLastSeen()) + "<BR>";
		}

		if (nodeStatus['state'] == "DOWN") {
			nodesD.push(nodeStatus['key']);
			var prevState = "";
			for (j = 0; j < nodesOD.length; j++){
				if (nodesOD[j] == nodeStatus['key']) prevState = "DOWN";
			}
			if (prevState != "DOWN")
				messageU2D += nodes.data[i].getEui() + " : " + nodes.data[i].getName() + " : " + mcApi.utils().friendlyTime(nodes.data[i].getLastSeen()) + "<BR>";
		}

	}

	if (messageU2D != ""){
		message += "Nodes DOWN: <BR>";
		message += messageU2D;		
	}

	if (messageD2U != ""){
		message += "Nodes UP: <BR>";
		message += messageD2U;		
	}
	
	if (message != "")
		//  mcApi.operation().sendPushbulletNote(null, "abc@xyz.com", null, subject, message);
		mcApi.operation().sendEmail("abc@xyz.com", subject, message);

	nodesVar.value = JSON.stringify(nodesU);
	nodesVar.value2 = JSON.stringify(nodesD);
	nodesVar.save();
}

@jkandasa it's probably related to some gateway issue, probably connected to the issue I asked here

I made a hard restart of the gateway and now the error disappeared.
Thank you!

@skywatch you could probably exchange messages thru MQTT queues, but being you I'd really invest my energies understanding how to use 2 gateways, since this is the standard way and you'll probably get more support for the community.
By the way, I have 4 gateways in my home (due to connectivity issue caused by concrete walls) and I never had issues with that in MyController.

@jkandasa I restart MyController Raspberry regularly (scheduled once per week), I tried doing that manually but nothing changed.
No changes on the router, but you made me remember I recently re-uploaded the sketches of my gateways and in this way I upgraded their mysensors library version.
I'll try downgrade one of them and see if this helps.
