Yup, not sure Nico has tried any 2.9 versions but probably the same issues on
both devices

Yup.

Generally through fhem (perl) which provides a basic set of commands, relevant
section (hoping it makes some sense) is...
[quote from OWDevice.pm]
$owdevice{"FF"} = {
# LCD - LCD controller by Louis Swart
"read" => [ qw(counters.0 counters.1 counters.2 counters.3

I think that follows the owfs L Swart manual pretty closely

I have been using
#!/usr/bin/perl -w
use OWNet;
my $owserver = OWNet->new('<IP_address>:4304 -v -C');
$owserver->write("uncached/FF.870900000100/line20.0","Hello World");
$owserver->write("uncached/FF.870900000100/line20.1","0123456");
$owserver->write("uncached/FF.870900000100/line20.2","abcdefg");
$owserver->write("uncached/FF.870900000100/line20.3","Bye");
for testing purposes both on server and remote
just tried
owwrite "/FF.870900000100/line20.0" "abcdefg"
owwrite "/FF.870900000100/screen20" ""
and all correct on 2.9p3

I keep going through the git log but beyond me at the moment.
I have tried debug on both but cannot see any significant differences using the
above perl script
Thanks for getting back
Andy
