Oh, found it.
Just the little pencil right to the text ‘Community’. Silly me.

Hi,

Today I registered 5 IMEI-numbers via the portal.
But no data will eventually be received.
And I think that is caused by the change in format.
Whereas I see only digits in the IMEI-numbers that are working correctly, I now see IMEI:IMEI in front of the IMEI-numbers that are not working.

Did something happen in the way we have to register? I did as always insert the 15 digit number and chose UDP.

I can confirm this. When I try to do a “search by IMEI” from the Device-tab in the Portal it always gives a “Something went wrong”-error.
I have no issues with losing data. Thatś all fine.

@rhalflex : Hi, no that is definitely not the data I expect.

Hi Afzal,

I just checked these three nodes but none of them sent anything. I.e. I don’t see anything coming on our application server. They should send every 12 minutes.

We have many (some 200) Sodaq-Sara nodes. Some of them suddenly stopped sending data in the last week or so. Strange is that I see that sometimes Time Of Last Message is less recent than Time of First Message. But that is not the case with all problematic nodes.

Here three nodes from which we don’t see data anymore. But we have more ‘problem-nodes’.

Is something going wrong?

I’m receiving messages again. Problem solved?
About lack of communication as @magnatron writes: I am not sure if I agree with that. Yes, it is hard to get in touch with T-Mobile. That needs to be improved. But once you have contacted them, they are very much willing and trying to solve your problem.
And, we have a ‘Community’-plan. I don’t know exactly what I can expect as support.

I have to confirm this. No messages since 2020-03-11T03:31:09.33449585Z
Same problem as last week?

Derko

I just contacted @Eric-Barten. They are aware of the problem and working on a solution.

Helllo T-Mobile and Robin,

Same here. No data arriving at our endpoint. Worked OK for months, but stopped at 2020-03-05T01:47:09
Hope it can be fixed quickly.

Best regards,
Derko

For citizien-science purposes we deployed several low-cost air quality sensors in The Netherlands using NB-IoT and a T-Mobile SIM-card.
Will such a configuration work in Poland?
Is there a way I can check T-Mobile coverage without going there? A bit like the LoRa TTN-Coverage Map?
