A night light with Node-RED and MQTT

By seb may 12,2023.

Last week, we saw that it is now possible to send commands to our modules from an MQTT broker. To illustrate this feature, this week we see how to make a "night light" using a Yocto-Color-V2 and Node-RED.

Extending MQTT support

By mvuilleu, in Internet of Things and New stuff, may 05,2023.

After the encouraging results of our integration of Yoctopuce sensors in Home Assistant via the MQTT gateway, we could not resist the temptation to integrate our actuator modules as well. But to do so, we had to start by improving our MQTT support by enabling MQTT to send commands to the modules. Here is a presentation of these improvements.

The SelectArchitecture method of the Python library

By seb, in Programming, april 21,2023.

Our Python library works on the three main OSes (Windows, macOS, and Linux). 99.9% of the time, everything works as expected and the library automatically detects the OS and the architecture of the machine. But under Linux, in rare cases, it is necessary to specify this last parameter manually. This is the job of the YAPI.SelectArchitecture() method.

Yoctopuce and Home Assistant

By mvuilleu, in Measures and Internet of Things, april 14,2023.

Even if Yoctopuce devices are more often used for professional automation than for private home automation, we already had the opportunity to present you some home automation applications: a ventilation system to fight humidity, a system to optimize watering according to the weather, etc. So we decided to study the possibility of integrating the monitoring of these systems on a standard home automation console: Home Assistant.
