Since my last message here is the result of my last tests:

Test 1
upload of the scketch without any modification from the site "MYSensor".
In Domoticz's log:

-discover the node:
2018-01-06 11:25:42.251 MySensors: Node: 5, Sketch Name: IR Rec/Playback
2018-01-06 11:25:42.252 MySensors: Node: 5, Sketch Version: 2.0

-at the touch of the "1" key of the remote control registered in 20:
018-01-06 11:25:49.388 (Mysensor) Light/Switch (IR Command)

-appearance of a new device MYSensor

-and in serial monitor of the Arduino IDE:
Received : 1 RC5 801 (12 bits)
Found code for preset #20
TSP:MSG:SEND 5-5-0-0 s=2,c=1,t=33,pt=1,l=1,sg=0,ft=0,st=ok:20

When I activate the device
-in Domoticz's log:
2018-01-06 11:26:55.759 User: Admin initiated a switch command (157/IR Command/Off)
2018-01-06 11:26:55.760 Error: MySensors: Light command received for unknown node_id: 20
and
"error sending command to the switch, please verify device/hardware"

-No events in serial monitor of the Arduino IDE.

Test 2
I made a new installation of Domoticz with the image "domoticz-raspberrypi-sdcard-4834.img".
Domoticz faith configured, I added my MySensor gateway alone without any other hardware,
after discovering the node and adding the device to the switches, an action on this device
and there oh miracle, it works!:+1:

Then I updated Domoticz to version 3.8153 and after that the device does not work anymore!:white_frowning_face:
and "error sending command to the switch, please verify device/hardware"

sorry, forgave me I would not do it again

I am having trouble doing IRSensor with domoticz.
After pouring the scketch into the arduino, saved my codes and
to check that it worked well with MYSController, here's what
I obey when I activate the device under Domoticz:

"error sending command to the switch, please verify device/hardware"

My material in place:
Domoticz V. 3.8153 sur Raspberry PI 3
Gateway USB MySensor V. 2.1.1 on Arduino Nano
IRSensor V. 2.0.0 on Arduino Nano

For information in the domoticz log:

-The node is well detected

2017-12-28 09:07:12.553 MySensors: Node: 7, Sketch Name: IR Rec/Playback
2017-12-28 09:07:12.554 MySensors: Node: 7, Sketch Version: 2.0

-When I send a pre-recorded order with the remote control

2017-12-28 09:07:59.346 (MySensor) Light/Switch (IR Command)

-When I activate the device in Domoticz

2017-12-28 09:08:29.835 User: Admin initiated a switch command (149/IR Command/Off)
2017-12-28 09:08:29.836 Error: MySensors: Light command received for unknown node_id: 6

Someone would have any idea?

Thanks for your help.
