Cannot retrieve the Error property

[jeroen-smit]

Version of the custom_component

v1.0.0

Describe the bug

The integration cannot successfully retrieve the Error property/attribute. After including "Error" for "Additional properties to poll" in the configuration UI panel, it shows property_error_error on Submit and will not proceed/save. See screenshot & debug log.

Note: This is with the Epson TW9400 (= 5050UB). The other properties retrieve just fine, and overall the integration seems to work wonderfully. It is however the Error property I'm particularly interested in, specifically "No signal", and for which I installed this integration :-)

I have the same challenge on my Epson EH-TW9400W.

By the way, there are a few more error codes nowdays, one might add the last few lines into /homeassistant/custom_components/epson_projector_link/projector/const.py:

PROPERTY_ERR_CODE_MAP = {
"00": ERROR_NONE,
"01": "Fan error",
"03": "Lamp failure at power on",
"04": "High internal temperature error",
"06": "Lamp error",
"07": "Open Lamp cover door error",
"08": "Cinema filter error",
"09": "Electric dual-layered capacitor is disconnected",
"0A": "Auto iris error",
"0B": "Subsystem Error",
"0C": "Low air flow error",
"0D": "Air filter air flow sensor error",
"0E": "Power supply unit error (Ballast)",
"0F": "Shutter error",
"10": "Cooling system error (peltiert element)",
"11": "Cooling system error (Pump)",
"12": "Static iris error",
"13": "Power supply unit error (Disagreement of Ballast)",
"14": "Exhaust shutter error",
"15": "Obstacle detection error",
"16": "IF board discernment error",
"17": "Communication error of Stack projection function",
"18": "I2C erro",
"1A": "Lens shift error",
"1B": "Quarts N Polarizer error",
"1C": "No lens error",
"1D": "Subsystem error 2",
"1E": "Power supply voltage error",
"1F": "Other error",
}

Btw. I can not find the "ERR?" command - or I can not read python code maybe is more correct...
