Automatically finds all 1wire devices and assumes them to be temperature probes. Specifically made for DS18B20 sensor probes in combination with Raspberry Pis. Useful macros: You can assign a friendly name for the probes using the following syntax: {$PROBE:”1wire-ID”} 1wire-ID being the devices name, found under /sys/bus/w1/devices/. The set value will represent the friendly name. You also have the option to assign sensors to three different groups: 0, 1 and 2. This will modify the trigger behaviour for specific sensors. 0 is using a normal temperature range calculated for server rooms, 1 is using an extended range and 2 is disabling triggers completly. You can see the specific values in the trigger section. The macro syntax for this is similar to the friendly name: {$GROUP:”1wire-ID”}
Specifically made for DS18B20 sensor probes in combination with Raspberry Pis. Could & should work on other systems aswell (eventually with small modifications) however it has only been tested on RPIs and DS18B20s.
This template will automatically find all 1wire devices and assume them to be temperature probes.
It’ll create items for every 1wire device it found under “/sys/bus/w1/devices/”, convert the output to Celsius (in the correct fashion for DS18B20 probes) and create six threshold triggers aswell as a “no data”-trigger for each one.
To better differentiate between the sensors you can assign a friendly name for probes using the following syntax: {$PROBE:”1wire-ID”}
1wire-ID being the devices name, found under /sys/bus/w1/devices/. The set value will represent the friendly name.
You also have the option to assign sensors to three different groups: 0, 1 and 2. This will modify the trigger behaviour for specific sensors.
0 is using a normal temperature range calculated for server rooms, 1 is using an extended range and 2 is disabling triggers completly. The macro syntax for this is similar to the friendly name: {$GROUP:”1wire-ID”}
The space limit unfortunatly doesn’t allow me to tell you the thresholds here, however you can quickly see them in the trigger sections.

Automatically finds all 1wire devices and assumes them to be temperature probes. Specifically made for DS18B20 sensor probes in combination with Raspberry Pis. Useful macros: You can assign a friendly name for the probes using the following syntax: {$PROBE:”1wire-ID”} 1wire-ID being the devices name, found under /sys/bus/w1/devices/. The set value will represent the friendly name. You also have the option to assign sensors to three different groups: 0, 1 and 2. This will modify the trigger behaviour for specific sensors. 0 is using a normal temperature range calculated for server rooms, 1 is using an extended range and 2 is disabling triggers completly. You can see the specific values in the trigger section. The macro syntax for this is similar to the friendly name: {$GROUP:”1wire-ID”}
Specifically made for DS18B20 sensor probes in combination with Raspberry Pis. Could & should work on other systems aswell (eventually with small modifications) however it has only been tested on RPIs and DS18B20s.
This template will automatically find all 1wire devices and assume them to be temperature probes.
It’ll create items for every 1wire device it found under “/sys/bus/w1/devices/”, convert the output to Celsius (in the correct fashion for DS18B20 probes) and create six threshold triggers aswell as a “no data”-trigger for each one.
To better differentiate between the sensors you can assign a friendly name for probes using the following syntax: {$PROBE:”1wire-ID”}
1wire-ID being the devices name, found under /sys/bus/w1/devices/. The set value will represent the friendly name.
You also have the option to assign sensors to three different groups: 0, 1 and 2. This will modify the trigger behaviour for specific sensors.
0 is using a normal temperature range calculated for server rooms, 1 is using an extended range and 2 is disabling triggers completly. The macro syntax for this is similar to the friendly name: {$GROUP:”1wire-ID”}
The space limit unfortunatly doesn’t allow me to tell you the thresholds here, however you can quickly see them in the trigger sections.
