Hi @grovkillen,

Must be magic, it just works, so simple! I was thinking something complex like putting it in as a variable and using substrings, mid functions in rules (if espeasy has those functions).

Now I can have low costs tm1637 in all my espeasy to show the ip without having to use fing or interrogate the router.

What other magic tricks you have?

Merry Christmas and Happy New Year to you and all in the forum!
Thanks,
Ken

Hi,
Works when I type the the cmd 7dn,%ip4% on the web interface, however with the rule it does not work:

on system#boot do
Pulse,2,0,1000
7dn,%ip4%
endon

The idea is of course to display the last ip oclet on start. Am I missing something?

Just as a test, try to have a timer in the boot event block that is set to 10 seconds. When the timer run out, set the text. It could be that the system variable is not set at the boot event.

Yep works with a timer delay, got it down to timer delay of 3 sec or more works, but under 3 secs does not work.
Thanks

Yep, makes sense since you haven't connected to the WiFi until after those 3 seconds.
