OK, the time has come to ask you for some help if anyone has done it better…
We need to make the UI of the LCD more responsive as it is very slow at the moment.
The actual problem is the browser rendering the screen changes on HABpanel. We are not sure if this requires momentarily more CPU or more memory (or both).
If you use your phone app or your laptop’s browser to change, say, the heating setpoint, you will instantly see the change on the LCD too. But if the input is FROM the LCD then it is slow (1.5-2sec)
If you run the same SD card from a Raspberry 3, of course you have no delays but using a Pi3 will make the project bigger (bigger PSU too), more expensive and will produce much more heat that will affect the temperature readings.
If anyone knows or uses some tricks, please share.
- Use OpenHAB (as it enables numerous integrations with external systems)
- Use HABPanel as it allow people to easily customise the UI to their needs
