How do I map a json input into different Assets?

Innovative

@peterMbari_twitter

@Kerruan use the change originator rule node and post the json as attribute or telemetry for the relevant asset.

Hi all,
I was hoping you can assist with 2 issues I have run into. The 1st is : How can I post process the 'active' attribute so that it's displayed in a widget as 'Online' or 'Offline' instead of true of false respectively? I have used the following command but the wording doesn't change state:
return value===true ? "Online" : "Offline";

Thanks

Chr1sK

@Chr1sK

The 2nd is: How can I update a server attribute when an inactivity event is received? When I try to update the attribute via a script and save the attribute I get an error around the msgType mismatch

Hello, I successfully connected to the server that is running MQTT over SSL using the sample two-way-mqtt-ssl-client python client code in thingsboard.io.But I wonder if anybody have tried the java client? I have to connect to thingsboard which is running mqtt over ssl using a java client (two-way-ssl) because of bussiness needs and I struggled with it for days still got the error "peer not authenticated" I used the microservice architecture. Does anyone have successful experiences to share?

Hello, I am trying to use control features in thingsboard. I came to know that this can be achieved using control widgets. Can somebody help me, receiving the value changed by the control widget in the python application?

hi guys, do you know if it's possible to define a TTL for an alarm? My goal would be to have the alarm automatically cleared/deleted after 12 hours

What is the command to restart the thingsboard service

Anita

@anitakh96_twitter

@peterMbari_twitter do I have to set it manually? have you done that yourself?

Is there a way to add custom commands for api calls in the thingsboard api ?

@bhankris

Hi, I'm unable to see the alarms from multiple devices in alarm widget.
I see couple of questions regarding the same issue in the forum (thingsboard/thingsboard#979) and (https://gitter.im/thingsboard/chat?at=5cf0cd0e481ef4167ba65d1a), not sure if it's resolved yet.
I'm running the latest thingsboard CE from docker with postgres.
Any reply/help is appreciated.
Cheers

@anitakh96_twitter I set up my GSM/GPRS device as a gateway, I was able to simulate Device A, Device B. The gateway also behaved as a device by publishing to device telemetry topic and recived rpc by subscribing to device rpc topic, So in total I achived three devices in one.

Innovative

@peterMbari_twitter

@anitakh96_twitter to and test RPC, it is easiest from a dashboard. Insert a control widget, like a switch. When you flip the swich if your device is subscribed and connected, you should be able to receive the RPC. To mitigate for latency in slow networks, increase the timeout period in the widget settings

Anita

@anitakh96_twitter

@peterMbari_twitter which topic should I subscribe from device?

Is the originator stored in metadata or how would I change the originator in a script?

Innovative

@peterMbari_twitter

@Kerruan use the rule engine to change the originator.

shjanaki

@shjanaki

Hi All, I am trying to get the sum of all devices and also the count of active /vs inactive devices and gateways , is there any easy way of doing it in thingsboard / apart from going thru rule chain to process active /inactive rule chain

@ghost~5dd7a363d73408ce4fd1cce5

@peterMbari_twitter Thanks but only works for related entities however I don't want them to be related, any idea how to achieve that?

Hi guys, how does proper response look for getValue method (control knob widget). I tried curl -v -X POST -d "44" https://cloud.thingsboard.io/api/v1/xxxxxx/rpc/215 --header "Content-Type:application/json"
Of course I update value of ID each time but none of it work. I would like that knob value changed after I send response

@starduszt

Hello all, Can you provide me with a step by step procedure of using port 8883 with Arduino and thingsboard? It always doesn't connect and I think it's because of the certificate that I don't know how to use. SOS. Thank you.

Hi, did anyone has installed trendz analytics? i cant find documentation for how to install..

MC3 Cardiopulmonary

@MC3-Cardiopulmonary

@jaimermneto_twitter - You have to call them for a demo. They don't have a CE version of Trendz.

jaime

@jaimermneto_twitter

Ok, i understood. I am using the PE version. They dont said anything about licensing of Trendz, maybe its included in PE Licensing?

MC3 Cardiopulmonary

@MC3-Cardiopulmonary

@vgtom Google: Thingsboard build from sources

Geir Andersen

@GeirFrimann

@jaimermneto_twitter It is not included in the PE version, its an add-on, I had an online-meeting with them earlier today, where Trendz was presented.
But if your solution heavely depends on analyzing data, its worth concidering!

@Sliosas

Is it possible to use two ports for mqtt: 1883 for localhost and 8883 for remote connections? I looked at the /etc/thingsboard/conf/thingsboard.yml file, but it seems to only have one input for address and port.

@Waynedejager1

Hi . I am looking for a developer that can help me with thingsboard. ( not even sure if thingsboard is correct for my application ) but essentially i want to use sensor data from a device and by possibly using "rules engine" create a bill by adding value to sensor data totals. The billing is not for monetary purpose but for cross reference with a utility charge. I am looking to pay for a developer to create this for me - any devs out here who could help? willing to pay a few hundred dollars

We have a total of 100 clients and each client has 10 devices.
So when a client logs in we need to show only his 10 devices in his dashboard.
can we achieve the same thing using thingsboard?

Chris-O2

@Chris-O2

@bryamabril_gitlab
Hi Bryam, Thingsboard is downloaded and installed on a server - either on a VM / Physical or setup in Containers. You have to supply your own storage setup. There are guides on the website for setup
