Hello,

 

I own 8 HS110 for my home automations with Homeassistant since June 2020.

Since nearly 2 weeks 6 of this 8 HS110 lost the connection to my wlan and can't reconnect. (WLAN led blinks green)

The months before they have worked very well.

If I disconnect them from the power source and plug them in again, they are available in the Kasa app for about 15 minutes until they disconnect again.

In this short time also the energy management is available.

 

I've switched my 2.4HGz WLAN to a fixed channel (tried different), disable 5GHz, reset the HS110 and install them again...nothing helps.

The HS110 with hardware version V4 are not affected by this behaviour (2 of 8)

Also all other WLAN devices have no problem with the WLAN connectivity.

 

I can see in the logs of my Fritzbox 7490 that the HS110 plugs disconnect and reconnect in the same second but disconnect after 1min again and so on.

All 6 HS110 V2 create about ~100 dis/reconnects in 10min.

So no remote control is possible, even the Kasa app can't control them. (greyed out)

 

No updates were performed for my Fritzbox or the HS110 (blocked internet connection, because of the FW update which closes the local port)

 

Does anyone have an idea how to fix this behaviour?

Are there some logs of the HS110 which I have overlooked?

 

Some Soft/Hardware information:

6x HS110

  - HW: V2.0

  - FW: 1.5.6

2x HS110

  - HW: V4.0

  - FW: 1.0.4

Fritzbox 7490

  - FritzOS: 7.21

All devices use a fixed IP address

 

Best regards
