Rules, clear line display not working

[marktn]

Hello!

I have an espeasy with a Display - ST7789 TFT and RFID - PN532 .
Tft works fine with http rules from domoticz.
Only sometimes it has a delay when it reads a tag, sends it to domoticz, and domoticz send a http rule that the tag is read.

So i thaugt lets do that in the espeasy rules. Never used it. It works, but it is not clearing the line after 2 seconds. What is wrong i my rule?

Code: Select all

on RFID#Tag do
  st7789,txl,10,   ****Tag-detected****:
  timerSet,1,2
endon

on Rules#Timer=1 do
  st7789,txl,10,                    
endon

I never used the plugin but try:

Code: Select all

st7789,txl,10,""  

Edit: Probably it's a good idea to wrap your text always in quotation marks.

The timer should be okay?

Not sure what kind of quotes you used, but text containing commas or spaces should be wrapped in a pair of (the same) quotes, either double quotes, single quotes or backticks.

To erase your initial message, just put the same amount of spaces (wrapped in quotes) as the original text message at the same line:

Code: Select all

on Rules#Timer=1 do
  st7789,txl,10,"                        " // Erase message
endon

NB: Rules script is trimmed of spaces and comments removed before being processed, that's why your line containing only spaces doesn't work.
