Mi Air Purifier stats plugin for Munin monitoring tool.
The plugin monitors all significant parameters measured by Mi Air Purifier devices. Those are: AQI and average AQI (μg/m³), humidity (%), temperature (°C), filter life remaining (%), filter use (h), device total use (h), purify volume (m³) and motor speed (rpm).
It should be compatible with all devices specified in the python-miio AirPurifierMiot's device class (under _MAPPINGS), however it has been tested with Mi Air Purifier Pro H.
In order to configure the plugin one has to obtain the device token (HOWTO).
Tuya WiFi Smart Plug power stats plugin for Munin monitoring tool.
The plugin monitors basic power parameters (current, power, voltage) that are measured by a wide range of WiFi smart power plugs compatible with Tuya IoT Platform and Smart Life application (tested with Gosund SP111).
The plugin utilizes the tinytuya Python library to collect the metrics. For devices running the latest protocol version 3.3 it additionally requires to specify an encryption/decryption key to exchange data with each device. The procedure of obtaining such key is documented on the library's page (the idea is to link your devices between the Smart Life app and the iot.tuya.com portal and authorize the Device Connection Service to fetch the list of registered devices, including their secret keys).
Tuya WiFi Temperature & Humidity Sensors Munin Plugin for Munin monitoring tool.
The plugin monitors temperature and humidity from various sensors compatible with Tuya IoT Platform, most often powered by AAA batteries.
Due to their mobile nature, the sensors do not offer the possibility of directly querying data from the devices; they send data updates every hour. The plugin collects data downloaded directly from Tuya IoT Platform by an auxiliary script and stored in temporary files. The script can be scheduled to run every half hour (there is no need to update the files more frequently).
It has been tested with the following WiFi sensors: TH01, TH08.
The plugin reads the estimated runtime values from all UPS-es that are configured in the upsmon's configuration file (upsmon.conf).
Each device has to return a valid ups.runtime parameter once the configuration is read by upsc, which for some drivers (eg. blazer_usb) may require to be configured through a manual calibration. Otherwise, without this parameter set, the UPS will not be shown.
Raspberry Pi Sense HAT board triple sensor plugin for Munin monitoring tool.
There is also an alternative version available with an additional 1-Wire DS18B20 digital thermometer defined, used for measuring the outdoor temperature.
A variation on the original load plugin from the Munin Plugin Gallery, inspired by Cacti's load average graph and color scheme. The plugin displays load averages as a stacked graph, showing the 1-minute, 5-minute, and 15-minute averages. An alternative version is also available, where 5-minute and 15-minute averages are represented by linear graphs.
PyGTK-based tool for sending broadcast frame called Magic Packet to turn on a computer remotely (tested in local networks and Internet). The program uses remote or local Top-level Domains list downloaded from IANA to validate the FQDN (can be updated by --update-tlds option).
There are two ways to use Wake On LAN over Internet:
You can send Magic Packet directly to broadcast address. For example 23.12.78.56/255.255.192.0 will send MP to 23.12.127.255.
If the computer is behind NAT you need a special iproute2 and iptables rules to forward broadcast messages.
Example:
#
#
The example above works for 192.168.0.0/24, where 192.168.0.254 is an unused IP, eth1 - WAN interface, eth0 - LAN. The iproute2 command assigns 192.168.0.254 address to MAC ff:ff:ff:ff:ff:ff. The iptables command forwards received packets from port 48777 to 192.168.0.254:48777 - this address has assigned the broadcast MAC, so all packets are sent to every computer in LAN.
A simple bash script that checks whether a defined number of Irssi processes are running per user and kills any additional instances, based on process creation time, keeping only the oldest one(s) active.
Real-time backup script which periodically checks modification time of each file and creates backup of the file if it has been modified, with preserve the file and parent directories structure and permissions.

Fix for some buggy sed df regular expressions:
- now it parses uniquely all filesystems (especially virtual filesystems)
- warnings/criticals for /rom filesystem are disabled by default
- DF_IGNORE_FILESYSTEM_REGEX can still be used to exclude any filesystem

This is essentially electronic atmosphere music designed to relax the listener with its soothing vibes. Generally under 90 bpm or totally beatless, ambient music takes you on a relaxing or thoughtful journey using a variety of sounds, from wind and whale sound samples, to richly textured electronic landscapes.
