device telemetry page is at 1970

Question

I have a data converter that generates the following output

[{
    "deviceName": "meter 34936959",
    "groupName": "All",
    "ts": 1579788289,
    "values": {
        "counter": 2686
    }
}]

timestamp is 1579788289, which is Thursday, 23 January 2020 14:04:49 but in the device page, latest telemetry is "1970-01-19 08:49:48"

can you please help me to understand what is wrong with the structure?

Thank you

It would be useful for answerers if you could explain how you are generating this JSON and where you are sending it. For example, a link to the telemetry API you are using. In this case, it is clear what the problem is regardless, but a bit of context is handy (and will help other people with the same problem find the answer). — sunil, Jan 23 '20 at 14:53

It is expecting a timestamp in milliseconds, but you are supplying a timestamp in seconds.

There is an example of this in the ThingsBoard documentation:

In the example above, we assume that “1451649600512” is a unix timestamp with milliseconds precision.

If you can't get the millisecond timestamp, try multiplying your timestamp by 1000 before sending it. With your example, that would be:

[{
    "deviceName": "meter 34936959",
    "groupName": "All",
    "ts": 1579788289000,
    "values": {
        "counter": 2686
    }
}]

Thank you!! I was expected to see this information also here: https://thingsboard.io/docs/user-guide/integrations/#data-converters — Aviad, Jan 23 '20 at 19:50
