Is your parse_rgbw_string() tolerant against \n?

Was genau ist dein Problem damit? Ich kann dir das Testen deines
DS2450-Klons nicht abnehmen, meist sind es Kleinigkeiten, die einem
einen CRC versauen.

Please see module/owlib/src/c/ow_2450.c:392 -- OW_w_mem()
423: if ( CRC16seeded(buf, 3, offset + i) || (echo[0] != p[i]) ) {
So, it's indeed seeded with 8+1 == 9.

Hi,
http://owfs.org is down, it shows
Bandwidth Limit Exceeded
The server is temporarily unable to service your request due to the site
owner reaching his/her bandwidth limit. Please try again later.
Temporary failure? Something more serious?

To sort out problems with CRLF, please set up owserver and use the

We need /etc/owfs.conf and a list which owfs services you run in
