Pseudonymous developer “Supply Simian” has launched a software designed to map general-purpose enter/output (GPIO) pins on the Raspberry Pi and comparable single-board computer systems to MQTT matters: mqtt-gpio.
“It helps enter and output pins; teams of pins; and sophisticated inching. Configurable with YAML,” Supply Simian writes of his creation. “I run it in K3s on Raspberry Pi OS. The service is constructed on gpiozero so ought to work on different gadgets. It’s a very useful constructing block in my DIY dwelling automation system. It is a basic goal connector so it may be configured for a lot of totally different makes use of.”
Designed to run from a container, mqtt-gpio is shortly and simply configured via a single YAML file. As soon as put in and configured, it connects to any MQTT dealer and binds a single GPIO pin or a set of GPIO pins to a given MQTT subject.

Pins linked to MQTT matters could be configured as inputs or outputs with optionally available pull-up and pull-down resistors configured, together with a user-configurable debounce time. If a specific payload is obtained, a collection of steps could be triggered — every step, naturally, being absolutely customizable.
“I constructed mqtt-gpio as a result of I could not discover an answer to with the identical capabilities,” Supply Simian explains. “I need it to be a undertaking that’s fast and simple to stand up and operating, and helps open up MQTT to anybody.”
The supply code for the undertaking has been printed beneath the permissive MIT license on GitHub, whereas a pre-built Docker container is obtainable on Docker Hub.
