Communication between 2 pi each running mycontroller

skywatch — Mon, 04 Jan 2021 14:32:21 GMT

@daniele Thanks for the suggestions. I know I can get the end result I want with operations so probably go that route for now and see what new surprises version 2 brings!

How to build a new gateway adapter to accept REST request?

jkandasa — Wed, 25 Nov 2020 07:17:32 GMT

@xuch74 you have to create your own REST API server, that server should act as a REST-MQTT adapter. On MyController create a mycontroller device type gateway with mqtt and add topic details from your adapter.

@Avamander Thanks for the pointer. Discourse needs more resources than NodeBB. We do not have that much budget. So, for now, we do not have any plans to upgrade.

Programmatically reboot a node

jkandasa — Wed, 08 Jan 2020 12:46:53 GMT

Probably a stupid question, but will this reboot all mys GW attached to the pi? @skywatch Yes, it will. if your mys GW powered by RPI

servlet independent mycontroller

@guisz1 There is no uncoupled version. But you can change the server easily on here. The undertow may fit easily.

Changing gateway type

jkandasa — Sun, 15 Sep 2019 15:29:18 GMT

@Daniele Changing gateway type will not impact your data/settings. I hope you are changing the gateway, the underlying node structure will remain the same. I recommend taking a backup prior to this action.

Action on node connected?

skywatch — Mon, 10 Jun 2019 21:07:48 GMT

That sounds promising - I was thinking of having a 'beacon' node in the car that would turn on outside lights whenever I got within range and it was dark outside. I could also have the controller send any warning messages (like alarm activation) to the car.

gpio shutdown from within mycontroller?

jkandasa — Thu, 07 Feb 2019 12:41:59 GMT

@skywatch Do you think it will be an issue with mcagent also running? Could there be a conflict with both python and mcagent trying to access the gpio ports? If you access the same pin from both side(Python and mcagent), it may conflict. Otherwise no issue.

Gateway type and performance

jkandasa — Thu, 17 Jan 2019 10:05:02 GMT

@Daniele Personally I do not see any performance difference/issue when using MQTT.

notification on node down status

jkandasa — Thu, 03 Jan 2019 21:40:41 GMT

@Daniele Your code looks super cool and awesome. I just added few HTML template style (you may not like ) and minor tune. Thanks for the awesome code!! 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"); // It is good to have key in lowercase and no space var nodesOU = JSON.parse(nodesVar.value); var nodesOD = JSON.parse(nodesVar.value2); var nodesU = []; var nodesD = []; var subject = "[MyController] Nodes status"; var tableBody = ""; for (i = 0; i < nodes.data.length; i++) { var nodeStatus = { }; var _nodeId = nodes.data[i].getId(); // nodeId is unique and internal // but still if you want to refer node EUI and gateway id, use the following line and comment above line. //var _nodeId = nodes.data[i].getGatewayTable().getId() + '-' + nodes.data[i].getEui(); var _nodeState = nodes.data[i].getState(); nodeStatus[_nodeId] = _nodeState; // update in to our common map if (_nodeState == "UP") { nodesU.push(_nodeId); var prevState = ""; for (j = 0; j < nodesOU.length; j++){ if (nodesOU[j] == _nodeId) prevState = "UP"; } if (prevState != "UP") tableBody += "" + _nodeId + "" + nodes.data[i].getName() + "" + nodes.data[i].getEui() + "" + _nodeState + "" + mcApi.utils().friendlyTime(nodes.data[i].getLastSeen()) + ""; } if (_nodeState == "DOWN") { nodesD.push(_nodeId); var prevState = ""; for (j = 0; j < nodesOD.length; j++){ if (nodesOD[j] == nodeId) prevState = "DOWN"; } if (prevState != "DOWN") tableBody += "" + _nodeId + "" + nodes.data[i].getName() + "" + nodes.data[i].getEui() + "" + _nodeState + "" + mcApi.utils().friendlyTime(nodes.data[i].getLastSeen()) + ""; } } if (tableBody.length > 0){ var pageStart = "Hello,

"; var tableStyle = ''; var tableEnd = '

Id	Name	EUI	State	Since

'; var pageEnd = "

--MyController.org
"; // mcApi.operation().sendPushbulletNote(null, "abc@xyz.com", null, subject, message); mcApi.operation().sendEmail("abc@xyz.com", subject, pageStart + tableStyle + tableBody + tableEnd + pageEnd); } nodesVar.value = JSON.stringify(nodesU); nodesVar.value2 = JSON.stringify(nodesD); nodesVar.save(); } Email will be looking like this, [image: 1548079561113-310032a4-3e1b-4191-9c0e-c42d7a1ff5f0-image.png]

Plans for ESP32 boards??

Ah okay, and what exact errors do you see? (never compiled this, but I can see if I am able to help you...)

JSON parser

skywatch — Tue, 27 Nov 2018 12:19:17 GMT

@Emenike It is free. There are no api keys needed. You go to the main Metcheck page, select your location for the weather location you want to use, then towards the bottom of the page is a button labeled 'JSON'. Click that button and it gives you a url to use (just modify the script above for the url it gives you) Sripts are under Utiliries menu in my controller main page. After that manually running the script fetches data fine, but from there on you will need jkandasas help as this is as far as I have got.

serial mqtt adapter

jkandasa — Wed, 07 Nov 2018 16:31:37 GMT

@cslauritsen Yes, it should work. MySenosrs serial Gateway <--> serial2mqtt <--> MyController(MQTT gateway)

Multiple Dashboards

jkandasa — Tue, 30 Oct 2018 12:57:34 GMT

@skywatch This could be a nice idea. But I never experienced this kind of setup. Can you assign node id for NRF24l01+ which is attached with RPI? AFAIK, it should be a gateway node right? If yes, we should not have more than one gateway node in a network. My other easy solution, Keep RPI with a private wifi router, hide ssid and do not connect to the internet. In this case, you can have a controller in one place and from another place you can access the controller via your private router.

Extended backup options for future release please.

jkandasa — Tue, 02 Oct 2018 11:22:21 GMT

@skywatch thanks for the feedback. Option #1 will be good. unfortunately, we cannot support Option #2, whole system backup. We can run MyController on many platforms(Linux, Windows, Mac, etc.,), it is very difficult to maintain the backup code.

Request: Within a graph, sensor variables should have consistent color

jkandasa — Fri, 21 Sep 2018 17:59:21 GMT

@skywatch I guess the color will work only with "A sensor graph", Not for grouped and mixed. In these graphs colors will be chosen randomly(we may have more than one same type variable in these graphs).

Request: Make all graph x-axis a consistent range [current time - (hour,day,week...), current time]

Node EUI on Topology chart

@jkandasa said in Node EUI on Topology chart: @Boggie This feature is available in snapshot version. .. and it looks fantastic

Android widget from switches/temps/hum etc.

Tag — Sun, 17 Jun 2018 19:01:47 GMT

@skywatch I have not seen V2 yet, but it certainly will be great to have a more mobile version of mycontroller.
