Better start from the beginning.
What I need to change in the code or configurations (MyConfig.h) to work the physical switch when the failure of the gateway.
Thank You

@mfalkvidd
I would like to control physical switch even if the gateway is unavailable (use domoticz and this project https://www.openhardware.io/view/77/AC-DC-double-solid-state-relay-module).

Now physical switch works only when is communicating with the gateway.

Thank You

@Fabien

Still is problem with physical button when gateway is not responsible.( i can not off and on the lights )
For example, when a server domoticz failure.

Hello, two month ago i asked question

In this topic: https://forum.mysensors.org/topic/3671/ac-dc-double-solid-state-relay-module/93

"Hello.
I would like to ask whether it is normal that the switch does not work if the server domoticz off? I want to use the switch only crash server now i cant"

And i got a reply from @hek it will be in the new library.(post 90)
Now i see 2.1.0 , and i have question now it is work?

Thank You

whose sketch you used? because I have a problem with phisycal switches if I use sketch of Nca78 (I wrote about this earlier)

@ludoarchi ![alt text]

Hello.
I tried to upload my two boards ( arduino pro mini 8Mhz , 3,3 V ) modified sketches but returned to sketch Nca78 (with DS18B20), unfortunately, does not operate a physical switch. Sometimes phisical switch changes state in domoticz ( not every time ) but relays do not change state.
Switching on and switching off the lights of domoticz changes state relay without a problem.
What could be wrong ?

It possible implement this option in mysensors 2.0 ?

You can disable this behaviour by defining:

#define MY_TRANSPORT_DONT_CARE_MODE
#define MY_PARENT_NODE_ID 0

sorry for the ridiculous question but I have to enter into a sketch? or MyConfig.h?

Thanx for the answers
This is not good news from the switch does not work without a server. Mr.const, Do you use esp8266 in domoticz to control the light?

edit: hek, I not noticed your post.
What changes adding this?

#define MY_TRANSPORT_DONT_CARE_MODE
#define MY_PARENT_NODE_ID 0```
