Nextion Handler version 0.5 is now available.
The 3 new main features this version adds are:
- New commands for controlling your Lights (setlt, lt_brt, lt_ct, lt_rgb, lt_hs, lt_cw, lt_wt), including color wheel control and a generalized ‘pop-up’ page of light controls (use as a template).
- New commands for working with Persistent Notifications (setntf, ntf, ntfx), including a ‘pop-up’ page for notifications (use as a template).
- A robust implementation of ‘swipe’ and ‘press’ touch GESTURE controls on the Nextion (which will likely to be useful to anyone still trying to get these to work reliably in their own projects).
I have also completed the documentation on GitHub, so it should be much easier to understand the example HMI files and to create/adapt your own.
The approach is working very well on my own devices (example below):
