But if i change the lcd-config-schema.coffee default and remove "address" from config.json pimatic startup without errors:
module.exports = {
title: "lcd plugin config options"
type: "object"
properties:
bus:
description: "i2c bus device"
type: "string"
default: "/dev/i2c-1"
address:
description: "address of the device"
type: "number"
default: 0x20
rows:
description: "number of rows (lines) of the LCD"
type: "number"
default: 2
cols:
description: "number of cols (characters in a line) of the LCD"
type: "number"
default: 16
but if i set a rule like this it will run and say "displaying xx on line 1" but nothing happend on line 1
"rules": [
{
"id": "aa",
"name": "aa",
"rule": "if $syssensor1.cpu changes then display "CPU: {$syssensor1.cpu}%" on lcd line 1",
"active": true,
"logging": true
}
i also see in my logs a error in the first install of pimatic-lcd:

It looks like something (address) is hardcode or the installation was wrong...
