I have a Nextion 3.5" display that I would like to use on my desktop.
This file doesn’t exist. Is there another source for the 3.5" Nextion?
Yeah, Nextion panels are sometimes better used upside down due to their viewing angle, so using the HASwitchPlate-Inverted.tft and then mounting the device upside-down in your work box might be a solution. No other modifications should be needed, blueprints etc will all work as designed.
If you open the project HMI in a Nextion editor you can directly examine individual elements which might be helpful in your explorations. In the image below, I selected page 1, then clicked on one of the buttons, which presented me with the 4 color codes assigned as defaults to this particular object:
I can confirm the behavior you are seeing with page 2 in scroll mode. No idea what the heck is going on there, but it’s happening here too. I created this bug in the issue tracker and have assigned it to myself, thanks for the report!
It sort of worked. The display did invert. But, now, my HASP is bricked.
On the display, I see the WiFi is connected, but no mention of MQTT.
Cycling the power a few times didn’t change the result.
I removed the HASP from the wall and opened it to insert the MicroSD and flashed
https://raw.githubusercontent.com/HASwitchPlate/HASPone/main/Nextion_HMI/HASwitchPlate.tft
to the Nextion.
Now, HASP boots OK.
I wonder if the OTA update was the problem? I’ll try a microSD card with the inverted.tft file.
UPDATE
Hard-flashed the Nextion with the inverted.tft file → No difference. It never got past the “WiFi Connected” screen.
I hard-flashed the HASwitchPlate.tft again, and after a couple of restarts, it now boots reliably.
Hi Luma,
I seem to be getting to following constant errors in the config log in HA:
2021-12-30 18:59:00 WARNING (MainThread) [homeassistant.helpers.template] Template variable warning: ‘break’ is undefined when rendering ‘{%- set color = namespace() -%} {%- for entity in device_entities(haspdevice) -%}
{%- if entity|regex_search("^light…*selected_background_color(?:\d+|)$") -%}
{%- set color.source=entity -%}
{{ break }}
{%- endif -%}
{%- endfor -%} {%- set brightness = state_attr(color.source, “brightness”)|int / 255 -%} {%- set red=(state_attr(color.source, “rgb_color”)[0] * brightness)|int -%} {%- set green=(state_attr(color.source, “rgb_color”)[1] * brightness)|int -%} {%- set blue=(state_attr(color.source, “rgb_color”)[2] * brightness)|int -%} {{ (red|bitwise_and(248)*256) + (green|bitwise_and(252)*8) + (blue|bitwise_and(248)/8)|int }}’
You’ll need to update your blueprints! That error was fixed a few versions ago, so replace the contents of <home assistant>/blueprints/automation/HASwitchPlate with the files found here.
This process is annoyingly manual - if you’d like to help out, maybe upvote the feature request here which aims to make the blueprint upgrade process a little less of a pain.
Thanks, working great now
Hi. Is it possible to use the nextion editor to create pages for openHASP?
No, openHASP does not use Nextion displays or HMI files.
You need to create a JSONL file for openHASP.
Is there any other GUI-software to create pages and export to jsonl?
Help!
I had HASP running on a larger screen with jumpers to a wemos. Worked great. It was named “desktop”.
Since then I built a desktop version using the correct display. Works great.
I wanted to change the first desktop unit name from “desktop” to “lab” for experimenting.
This is where things got bad. When I plugged in the original Wemos, Home Assistant “discovered” a new device named “desktop”. (Yes, I should have unplugged the desktop unit before plugging in the lab unit).
So, now in Home Assistant I get this:
On the “desktop” HASP, all I get is the empty Page1.
How do I fix this? Erase everything and start over?
Try running through this guide.
When HASPone comes online, it send out a device discovery message with its device name and the “haspClientId”, which is a combination of your device name and the MAC address. If you rename the device, it should create a new device (but I don’t have any way to remove the old device). If you bring another device online with the same name, that will also create a new device because the other unit has a different MAC address which allows Home Assistant to recognize that this is, in fact, a different unit. Finally, Home Assistant will also create a new device with a new name, but because the name already exists, it will get a _2 appended.
Hoping someone can help me here. Desperate to try this project with my Nextion but i have fallen at the first step.
I have a NX3224T024_011, which I have flashed the TFT files to via SD card. I have flashed the HASPOne firmware to several different D1 mini’s (at least 4 different boards), all the D1 minis are known to work as I have previously used them for ESPHome projects successfully. I then followed the wiring and set up instructions on this page and yet I never get past the ‘HASP Initializing’ screen.
Am i missing something really simple here?
Assuming that flash went well, every time I’ve had that issue it’s been a data issue. Do you have the RX and TX swapped? Thats what it was the last time for me.
Yep, successfully flashes every time:

I have it wired as per the instructions on the link I posted:

I have tried swapping the pins around too, no success there either.
Thanks for your response @luma. I’m not sure how I can grab debug output; I can’t connect it to WiFi to give it an IP as it doesn’t get to the configure screen, so Telnet isn’t an option. If I’m reading your docs right, USB debug requires going into the web admin page on the device, which again, I can’t get to as it doesn’t get that far. Genuinely stumped as to how to go forward.
USB debug will be enabled by default until you go through the process of disabling it on the web admin screen, so if you’re just now flashing the device and haven’t yet gone through the configuration, chances are good it’s spitting out some useful information via serial that would probably help us figure out what’s going wrong.
Thanks. Didn’t know it was enabled by default. I checked the logs, connected to the fallback AP to configure Wifi and MQTT and still no luck, still stuck at ‘HASP initializing’ - here’s the output:

Allright, so the first thing I notice is that you’ve flashed the old project! You’re going to want to make sure you’re looking at the HASPone repo here, then follow this guide to flash your device.
