Re: NodeMCU doing many things!

The HC-SR501 and Nextion have 3.3V logic levels. So they are directly compatible with the ESP8266 and do not require logic level conversion. Use 5V to power them and wire their signals to the GPIO pins. - Thomas Thanks I understand their signals will be perfectly compatible. My question was concern...

I am using print "|s,i1,sOn" // Send idx 1 and value 1 to ESPEasy printh 0a // Required print termination character for simple on/off buttons.

NodeMCU doing many things!

Right now I have 2 NodeMCUs on my bedside table. One has a DHT22 (3.3v) and HC-SR501 (5v). The other has a Nextion 2.4in touchscreen (5v). Can I move the Nextion to the first NodeMCU and free up the 2nd for more projects? I'm wondering if I can pull 5v to the HC-SR501 and the Nextion and be 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 i...

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 seri...

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...
