Homekit not working until i reduce the amount of items

Hi,

i have a problem with the homekit 2.4.0 and 2.5.0M1 binding. For some reason it is impossible for me to successfully pair my ipad with. The pairing procedure stops without any issue except the ipad displays that it cannot pair…

As soon as I remove the majority of the homekit items, the pairing works but after I re-add some of them, the homekit items are displayed as “not responding” in the home app.

I have tired everything else. Delete the homekit.json with all backups. Do a clearPairings and a bundle:refresh but no success.

I’m currently running openhab in version 2.5.0M1 in docker, but i tired it aswell with 2.4.0.

These are the last log entries from homekit

Does anyone have an idea?

I just want to add that I have about 70 Homekit items of different types

How many items does the pairing work with and how many items does it not work with anymore?

thanks for your response. During my troubleshooting I found the new addon from @Tim_Harper which solved my issue. The new plugin seems to be much faster and not that buggy. Unfortunately the new plugin stops working about every 5 days. A simple restart of the binding solves this issue, but its still some kind of unsatisfying. I’m still investigating whats the cause of this. Any ideas?

@ccutrer may have some ideas. He’s running a rather large setup and has a lot of devices.

There are some fundamental limitations about how many devices can fit on a bridge. Eventually, we’ll have to have multi-bridge support in the OpenHab Homekit addon in order to overcome that limitation.

150 accessories is the max iOS will allow (counting the bridge itself). If you have fewer than that, but are still experiencing stability issues, it’s likely the protocol error I fixed earlier. You should try the latest build from https://github.com/hap-java/openhab2-addons
