Yes, this starts the temperature conversion on all bus
Thank You Jan,
I'll try to switch my sensors from parasitic power to regular power.
How to enable simultaneous conversion for all chips ?
this way ? echo 1 > /mnt/1wire/simultaneous/temperature ?

No, but it's the only way you can do a simultaneous conversion for all
chips, and this 19 times faster if you have 19 chips.
You cannot do a simultaneous conversion

Please,
can you be more specific ?
When I try echo "1" > /mnt/1wire/simultaneous/temperature, cat
/mnt/1wire/simultaneous/temperature return 0.

There's a command to convert temperature of all sensors in the bus, that's
the simultaneous conversion
Check owfs file system there's a file just for this
Check ds1820 datasheet too , that's interesting when you need speed

Hi, what do you mean with "do a simultaneous conversion and read the values
after the conversion is done on all sensors." ?
Could you please add example ?
I read data with cat /mountpoint/sensor/temperature.
If temperature sensor is powered, then reading is faster compared to
parasitic power ?

Sampling 19 temperature sensors one-by-one takes up to 19 seconds. This
is due to the lengthy A/D conversion process.

Just a dumb comment:
can you confirm that this is not a Zabbix problem? what do you get by running
"cat /mountpoint/sensor/temperature" when zabbix is not recording data?

Well there's always the possibility that there is a wiring problem, but
also there could be two processes competing for the same resource.
Is owserver and owfs running at the same time? Your configuration file
would have them both grabbing the same serial devices and stepping on each
other.
