Re: Nextion display plugin
Hi
my first controller is an OpenHAB MQTT.
So far that's right. I can also switch a GPIO via MQTT.
What must the command for the Nextion Modul look like?

Re: Nextion display plugin
@CHK_BLN: The Nextion plugin has few users. So I don't expect you will get the exact answer to your MQTT command question.
The Wiki information for command usage is here: https://www.letscontrolit.com/wiki/inde ... _Reference
When I follow the wiki information the MQTT command statement for your installation would probably be something like this:
Like you, my Home Automation system is OpenHab2. My installation sends commands to ESPEasy's Nextion using HTTP; I don't use MQTT to send commands to Nextion so I cannot confirm if my suggested MQTT statement works. No doubt you will need to experiment to find the winning solution.

Re: Nextion display plugin
@CHK_BLK:
I used the "MQTTlens" chrome browser plugin and tested sending MQTT commands to Nextion. It works as expected.
My ESPEasy Nextion device is called ESPEZ_Laundry. The text field on page 0 has attribute g1. The screenshot below shows how I setup the two fields (Publish & Message) and sent "Hello World" to the Nextion screen.

Re: Nextion display plugin
I am attempting to use ESPEasy (mega-20180809 version) which has Display - Nextion [TESTING] as a device. I'm using soft serial and GPIO-0 and GPIO-2 (D3 and D4 on my NodeMCU). I am unable to communicate with the display. I cannot send txt updates and I cannot receive presses from the screen. A wiki post a few pages ago mentioned needing a pull-up on the RX (or maybe it was TX). Anyway, I don't have that option in my device setup even though other people seem to. I was able to communicate between these devices with other non-ESPEasy software so I don't think my hardware is the issue.
Re: Nextion display plugin
@smartsoldier: GPIO-2 is the LED drive pin. Assign that pin to the WiFi Status (Hardware tab) and use another pin for Nextion.
The sensor "Pullup" check box found on earlier versions of the Nextion Plugin was a placebo. It didn't do anything, so it has been removed.
BTW, I don't recommend soft serial. There's plenty of discussion/explanation on the possible serial data corruption that may occur. The latest Plugin has introduced hardware serial to eliminate the problem.

Re: Nextion display plugin
I use kind of commands to control my ESP.
For some reason it works out ok in the ESP, but I get an error in Domoticz.
I vaguely remember it used to work fine in the past.
EDIT
When I do this:
in the browser I get
And with domoticz I get no error
Code: Select all

Re: Nextion display plugin
@BertB: Unlike GPIO, Nextion does not reply to HTTP writes. So you won't see a status response to your Nextion commands sent by the browser.
I suggest you retest with the browser and send commands that update some text fields (so you can verify HTTP writes to the display). If browser access is able to change text fields then the plugin is running Ok.

Is it possible to build the HTTP reply in the Nextion plugin? I rely on HTTP calls to send updates to the display.

Find the code shown below in Nextion.ino's PLUGIN_WRITE: section:

Your browser should now reply with a copy of the sent write action.

Re: Nextion display plugin
I managed to develop an easy way to update elements in the NEXTION, with HTTP messages send by domoticz.
It uses a small dzVents (LUA) script and the attributes of the devices in domoticz.
This can be handy if you want to sync with domoticz after a reset of Nextion.

I have taken your advice and switched up my TX/RX pins to 13 and 15 (D7/D8 on my NodeMCU) so I can use hardware serial. I disabled Serial Log File in Tools and now I can communicate just fine!!

Re: Nextion display plugin
Thanks for the advice again. You rock. Mind if I keep it coming?
I am testing the communication between Home Assistant and ESPEasy/Nextion. I am using ESPEasy MQTT Import to pull in some simple sensors, but then how do I post those values to my Nextion? Do I need to do some rule that will send the imported MQTT values through http to my Nextion (http://192.168.1.XXX/control?cmd=NEXTIO ... ure#Value1%)? I tried to use the Lines in the actual Nextion Device tab, but the %BedroomTemperature#Value1% isn't pulling the actual value, its just displaying that entire string.
Edit: Side note, I setup my NTP north america pool and set my longitude and latitude but I'm still getting a system time that is 4 hours ahead of my time. Can I adjust that somehow?
Edit2: I tried this rule
but it didn't work. That is supposed to update an element on my panel to 13 every time that MQTT topic is received. I'm watching the log and it is being received exactly as I have it written.

Re: Nextion display plugin
Typo? The BC517 is listed as a NPN Darlington, whereas it needs to be a PNP small signal type. The two transistors mentioned in the Nextion Wiki are popular parts found in USA electronic shops. Plus sold by an endless number of suppliers on eBay and Amazon. Typical online price is about 0.15 USD each and often sold by the Chinese vendors in a bag of 50 pcs for $1.00.I used a BC517 which I bought at Conrad or Farnell or any local Radio Shack type of store.
Your "Lines" command statement would look something like this:I tried to use the Lines in the actual Nextion Device tab, but the %BedroomTemperature#Value1% isn't pulling the actual value, its just displaying that entire string.

Re: Nextion display plugin
FYI, the Euro BC series transistors have a different pinout than American 2N or PN series parts. So don't follow the Nextion Wiki drawing when using the BC327.

Re: Nextion display plugin
How do I get the Slider to output its value through "idx" or "value"?
I am using
for simple on/off buttons.
I have
setup right now, which displays the value of the slider (h0) in a text box (t1). It also prints that value as raw number (0, 5, 100) for example. How can I incorporate these two ideas?
Edit: On another note, I can't use the "Resend Values (below) at Interval:" to constantly update a clock on my main page with
because it will also constantly send the latest idx/value and it makes my Home Automation system keep receiving that and it keeps activating the event (in this case toggle lighting).
Edit2: I had another idea about updating my clock. I am trying to do a simple http post at:
but the log is giving me this:
Why does it work fine in the "Nextion Command Statements (Optional)" section when I add it as a Line, but not when I do http?
Lol if I run the command from the Tools menu I get this:
I am using
Code: Select all
print "|s,i1,sOn" // Send idx 1 and value 1 to ESPEasy
printh 0a // Required print termination character
I have
Code: Select all
cov h0.val,t1.txt,0

Re: Nextion display plugin
You must convert the Nextion touch move event's slider val to a text string. Like this (see Nextion commands summary for details):How do I get the Slider to output its value through "idx" or "value"?
Code: Select all
cov h0.val,t0.txt,0
Code: Select all
print "|s,i"
cov h0.val,t0.txt,0
print t0.txt
print ",sOff"
printh 0a
Put the page0.t0.txt="%systm_hm_am%" command in the Lines Statement area and select an interval. Disable Resend Values.I can't use the "Resend Values (below) at Interval:" to constantly update a clock on my main page with page0.t0.txt="%systm_hm_am%" because it will also constantly send the latest idx/value and it makes my Home Automation system keep receiving that and it keeps activating the event (in this case toggle lighting).
Or make a timer rule and send it from the rule file.
http writes to Nextion plugin do not support ESPEasy system variables. Use Lines or rules if you need to work with the system variables.Why does it work fine in the "Nextion Command Statements (Optional)" section when I add it as a Line, but not when I do http?

Is there a more natural way to find your information page about Nextion?
Would it not be nicer to get to it through the supported sensors part?
I am more than willing to move my How to (under construction) to another part of the wiki.

Re: Nextion display plugin
@BertB
FYI, I revised the Nextion plugin with the PLUGIN_WRITE update you requested. I also reduced serial log traffic. But I haven't issued a pull request yet because there's ongoing improvements to fix ESPEasy's instability problems. I think it's best to wait for the developers (@TD-er) to make more progress before introducing any non-critical plugin changes.
I've been testing the new releases and ESPEasy is still not there yet. The memory leak issue appears to be fixed but dropped WiFi and persistent random reboots still occur.

Re: Nextion display plugin
Hi Quorle,
Not sure what you mean with I2C. The display only has a plain old fashion serial interface,
Re: Nextion display plugin
I meant the bus with I2C. That's why I always thought I could search the display on the I2C. But it all seems to be more difficult than expected. Especially if you have no idea how to program an ESP8266 yourself and write programs.
Re: Nextion display plugin
You don't need to do anytnihng, select the device plugin (nextion on the TEST or DEV build), select RX & TX, in the fields of the plugin send commands to display. you can use also rules or HTTP commands but the last two options do not work currently.

Re: Nextion display plugin
If you publish the value to a given MQTT topic you can have the plug-in MQTT import to get that value into a task and from there you can use rules to publish it to the nextion display.

Re: Nextion display plugin
You need a float only topic for the MQTT import to listen to. It cannot parse JSON.
