No text is displayed / nextion_return_data Invalid Variable name or attribute

[nathanstitt]

I had a very old HASPone sitting around that I finally installed, my guess these issues relate to older hardware but I'm not sure. Hopefully someone can point me toward additional debug steps or a firmware update I missed. Thank you in advance for any assistance!

The device does not display any text and no blueprints other than core appear to work.

I've updated to the latest firmware 1.06 and applied the LCD update for LCD model NX3224F024_011R

I am able to switch between the pages using home assistant and it does change the layout, but no text appears on the bottom row as it should. Adding blueprints appears to work, but they have no effect and do not display.

Using telnet debug, I see the below errors displayed (I named the device kitchen_switch):

 'hasp/kitchen_switch/state/json' : '{"event":"nextion_return_data","return_code":"0x1a","return_code_description":"Invalid Variable name or attribute"}'

The webpage shows this debug info:

Oh and I forgot to mention that the firmware update url site haswitchplate.com seems to be down, I downloaded firmware from
https://github.com/HASwitchPlate/HASPone/raw/b2c263eee772071df3abd3b464ad38737e848bfa/Arduino_Sketch/HASwitchPlate.ino.d1_mini.bin and https://github.com/HASwitchPlate/HASPone/tree/main/Nextion_HMI and uploaded them to the device page

I ran into the same issue and, after a little bit of debugging, discovered that it was because my HA instance had, for some reason, reset the states of the four light.hasplate1_{un,}selected_{back,fore}ground_color entities, such that

HASPone/Home_Assistant/blueprints/hasp_Core_Functionality.yaml

Lines 608 to 610 in 7cca66b

	{%- set red=(state_attr(color.source, "rgb_color")[0] * brightness)|int(default=0) -%}
	{%- set green=(state_attr(color.source, "rgb_color")[1] * brightness)|int(default=0) -%}
	{%- set blue=(state_attr(color.source, "rgb_color")[2] * brightness)|int(default=0) -%}

was throwing an attribute error during template expansion. Using the developer console to reset those got the thing working again.

Probably that hunk (and the ones like it throughout the source tree) should instead be something like

{%- set rgb=(state_attr(color.source, "rgb_color")|default([0,0,0]) -%}
{%- set red=(rgb[0] * brightness)|int -%}
{%- set green=(rgb[1] * brightness)|int -%}
{%- set blue=(rgb[2] * brightness)|int -%}

for whatever it's worth, the option "First-time HASP setup or reset" in the Core Functionality blueprint will re-create these devices for you in the event they wind up missing.
