Can't configure PIR

[wroblewski6]

Hello i have Sonoff bridge rf and PIR (motion detector) In console I get
01:55:45 MQT: tele/Bridge/RESULT = {"RfReceived":{"Sync":12470,"Low":420,"High":1220,"Data":"D691DE","RfKey":"None"}}

And i configure accessory like this

{
"accessory": "mqtt-sonoffrf-receiver",
"name": "Motion",
"url": "mqtt://192.168.1.16", as this is my rpi ip
"topic": "tele/Bridge/RESULT", topic of my Bridge RF Is Bridge
"username": "ppp",
"password": "ppp", My password and username
"rfcode": "D691DE", the code form PIR
"rfkey": "None",
"ondelay": "time in ms while the sensor is active, the default is 10000", Do I have to change it ??
"accessoryservicetype": "'MotionSensor' (default) or 'StatelessProgrammableSwitch'"
}

it does not work and I get error

the code was validated by son so this is not a problem.

Can you tell me what is wrong with my accessory??
