Connection Lost...Reconnecting

Hi Guys,

I need your help, because I assume, that sometimes my HA is loosing connection.
Why do I think that?
4 reasons:

  1. Sometimes when I am on Computer and working on HA, is see in the bottom “Connection Lost… Reconnecting…”
  1. My Hue Sensors detects me, but although I am using an automation, the lights keep off. (sometimes!)

  2. Some sensors detect me and say: “occupancy: detected” but then it takes about 10 min that they switch back to status “clear”

  3. I realise that most of my sensors switch between on and off several times per day at the same time. Example: hue sensor

FYI, my setup:
Raspi 4
Home assistant: core-2021.9.7 / supervisor-2021.09.6
Conbee 2

temperature sensors: Aqara
magnet sensor: Aqara
jalousie/louvre: tuya
movement sensor + lights: All HUE ( 2 bridges active, but I am switching all devices to conbee now)
Before I used Hue Bridges for sensors and Conbee for all lights.
The purpose of using the hue bridge was to adjust the sensitivity of sensors.
Last weeks I also lost connection to the sensors and therefore I decided to switch everything to conbee.

As far as I see, only the hue deviced are affected of the connection lost.
Do you have an idea how to solve this issue?

AK

What I will do this night is to open cmd in windows and say

Ping 192.168.X.X -t

Tomorrow i will see if I had a permanent connection to raspi.
If so, I have to change anything in my HA setups.

I am having the same issue. I am using a virtual machine on a Windows computer. Installed on two different machines and same issue on both. Lost connection, reconnecting on iPad app, iPhone app and main computer. Reconnection hangs up and nothing happens. Connection seems to be stable for 1 to 1.5 hours. No one seems to know how to fix this. Must be more then two people having it happen?
