Problem with opensky sensor

Been having an issue with opensky sensor the the past week or so. Doesn’t seem to load often on reboots, and when it does, will detect planes for very short period before stopping again. I checked the log, and found the below. I can’t tell from this what is happening. Anyone able to assist?

During handling of the above exception, another exception occurred:

It’s a known issue.

I thought maybe it had something to do with limited API hits. I searched for anything about changes to their policies, but couldn’t find anything (only the current policy, which mentions the 100 hits for anonymous users, but in the absence of finding anything about a change, assumed that was how it always was, and that HA was working within that). Even registered users only get 1000 hits per day. So I’m guessing this integration has very limited uses now.

Are there any alternatives for HA integration? I couldn’t find anything in any of the list of integrations. I have a Silver FlightRadar24 membership. Would be great if I could use that somehow.

Have you found a solution?

So basically, this opensky is useless, as it gets clogged extremely fast, and there is no way to add credentials. Sad, i was on a hype with it :frowning:


I have made FlightRadar24 integration
