Domoticz Nextion remote

[alexsh1]

I did order Nextion though some time ago and it is in my "to do" list.
The facie has just arrived. Hopefully I can finish it soon.

Stay tuned!

how is battery drain?

[alexsh1]

@gohan I did not have to charge the battery in 6 months. I am using Li-on 9v battery - I could have been more efficient with 3.7v one and implement a charger as well. I just did not bother.

Do not forget that the controller is on very briefly to do scenes and then you turn it off.

@gohan that’s the exact battery I’m using
It comes with a charger.

How do you wake the mcu? The screen uses serial

[alexsh1]

@gohan it is a top secret proprietary technology called a switch 😆😆😆

It’s very simple - you just do not need to have it on all the time. Alternatively you can put it up on the wall and use 240V as a power source

[gohan]

Ah, that's not fair 😁

Else there's a pretty simple thing called accelerometer, you can wake up you board with movement when you pick it up or with tap/double tap

[gohan]

In fact I was asking how do you wake the mcu with a tap on the screen, since I understood it uses only serial communication.

[alexsh1]

@nca78 that’s way too advanced. My principle is to keep it simple ;)

[alexsh1]

@gohan I was never thinking like that. The startup time is about 1sec. Given I’m obsessed with a battery life and the device is only used occasionally, I could not come up with anything better than the switch.
