humidity

Reports humidity from the onboard sensor.

Example:

$ humidity
8.90502

ipaddr

Reports the IP v4 address of the given device (default eth0).

Example:

$ ipaddr vpn0
192.168.1.3

smsip

Monitors IPs and sends an SMS if a change is detected.

Example:

$ smsip 004917112345678

The IPs are stored at /var/run/ in files like vpn0.ip. If these files are missing or if one of the IPs to monitor has changed, the internal GSM modem is used to send out an SMS in the form:

[hostname] ip change detected
wwan0: [IP]
eth0: [IP]
vpn0: [IP]

To regularly check for IP changes, use cron:

* * * * * /usr/bin/smsip 004917112345678

temperature

Reports internal (CPU, default) and external (enclosure) temperatures in degree celsius.

Example:

# cpu is default
$ temperature
72.981
# specify cpu sensor
$ temperature cpu
72.981
# enclosure temperature
$ temperature enclosure
55.5417

usage

Simple data usage logger script

installation

Copy the script to e.g. /usr/bin/

cp usage /usr/bin/usage
chmod +x /usr/bin/usage

monitor every minute:

- * * * * /usr/bin/usage eth0

usage log format

The log is written to /var/log/ to a file called usage_[DEVICE].log:

DA TI TX_C RX_C SUM TX_L RX_L SUM_L TX_M RX_M SUM_M 

DA current date TI current time TX_C tx_bytes as currently reported by the kernel (eventually adjusted due to reboots) RX_C rx_bytes as currently reported by the kernel (eventually adjusted due to reboots) SUM sum of TX_C and RX_C TX_L tx_bytes since last measured (increment) RX_L rx_bytes since last measured (increment) SUM_L sum of TX_L and RX_L TX_M tx_bytes since beginning of this month (actually this log file) RX_M rx_bytes since beginning of this month SUM_M sum of TX_M and RX_M

example log line:

2021-10-18 11:38:00 31832148 1191376080 1223208228 6528 266613 273141 76961 2174380 2251341

rotation

If the sum of all usage_*-files is above 500m (see the file to change this), the oldest usage log is removed.

current usage (/run)

In addition to the usage file, the current usage for the month is written to the files /run/usage_[DEVICE].rx (recieved), /run/usage_[DEVICE].tx (sent) and /run/usage_[DEVICE] (sum).
