I have a problem with Ultrasonic HC-SR04 plugin.
I have the plugin installed in the plugin section:
{
“plugin”: “ultrasonic”
}
and inserted this in the devices section:
{
"id": "ultrasonic",
"name": "Ultrasonic HC-SR04",
"class": "Ultrasonic",
"echo": 19,
"trigger": 16,
"timeout": 750,
"delay": 60,
"sample": 5,
"interval": 60000
},
if I restart pimatic then comes an error message in the GUI:
error[pimatic-ultrasonic]: Error reading Ultrasonic HC-SR04 with id:ultrasonic
what am I doing wrong?
