Accesories disconect from homekit

Good morning. I have a problem with the homekit accessories in an iphone 4 series.
I have installed hassio 0.68 and addon homekit with 6-7 accessories. everything works fine a couple of hours later if I go open homekit in iphone the accessories does not work. If I’m going to turn off and then turn on the iPhone, the homekit works great at other 2-3hours.
what could be the problem?

It seems to be that for some reason HomeKit doesn’t fetch new data after some time. Since the HomeKit component only pushes new states to HomeKit, the Home App might think that an accessory is unresponsive if nothing has changed for longer periods of time. A restart of the Home App usually helps.
