Ets connection closed by remote device - gjniewenhuijse - 16.03.2026

HW: LM5 Lite + Ext (i.MX6)
SW: 20240426
ETS: 6.4.0

When programming a device with ETS i received an error: connection closed by remote device 2.x.x (my new buttons).

How to solve this?

- It is possible to program the individual address
- It is not possible to program the application, also not the short option

What exactly is this new button you have? Is it maybe data secure?

Berker S8014xxx0, not secure

I just tried ETS 6.4 on my instalation and it worked all fine.
Is LM KNX address from the same line you trying to download?


RE: Ets connection closed by remote device - gjniewenhuijse - 16.03.2026

Yes same line, i can program the individual address en 99/100 times the app download doesn't work.

What about LM itself, what is the load and how is the bus traffic?


RE: Ets connection closed by remote device - gjniewenhuijse - 16.03.2026

cpu/io 0.23 0.23 0.12, memory 9%, knx/tp op
very low bus traffic.

Try rebooting LM, did you try any other device not just this PB?
