HS/FS Reboot a KNX device programatically? (via Homeserver Send KNX telegram or using LBS)

[Roeller]

Hello,

Is there a way to reboot/reset a KNX device using the Gira Homeserver (using Send IP/KNX Telegrams) or using an LBS?

• I didn't find a Baustein for it.
• I also tried using the Homeserver 'Send IP/KNX Telegrams' option, but that method can only do 'GroupValueWrite' to a GroupAddress. I need a 'T_ACK (S=1)' and 'RESTART (S=2)' to be send to a Physical Address.

Probably this has already been asked many times, but after multiple searches here and on Google I couln't find it.

I know that it isn't good knowledge to reboot a device... why should you? Well, I have a Theben OT (OpenTherm) Gateway and I have seen it multiple times being 'stuck' when the gas heater (a NEFIT/Bosch device) was giving an error code for a few hours (like: Please, fill water, pressure to low). I don't want to turn down the power of the whole KNX system or unplug the OpenTherm gateway in those cases. I just want a button 'restart OpenTherm Gateway' in the Quadclient

I asked this already years ago and did get the same response (NONE). Also there was no info elsethere I could use. IMHO, I think this is not possible. I had a similiar Problem, and now I'm using a normal KNX actor as a solution.

I don't know HS at all, but if it can run arbitrary Python scripts you could use xknx to send the restart telegram. Otherwise any other computer can be used (RaspberryPi etc if you like).

But if the device really has crashed it is also not clear if it will react to a Restart telegram

Ich kenne das Problem und habe mir diese Funktion auch schon für den HS gewünscht.

you can disconnect the device with a switch actuator from the bus

The problem is that XKNX is only for Python3. Otherwise I had imported that into a new building block and had build a BUS_RESTART building block...

It's a day before 2022 - I'd say the problem is something still running Python 2 😱
Especially if it is a 2k€ Device that's still sold and updated. But maybe nostalgia is just not for me 🤣

Python 3 is here for >15 years, the original sunset of 2 was planned for 2015 🐍
