A weather station with MQTT and Node-Red

By thibaut, in DIY and Internet of Things, december 07,2018.

We already discussed home-made weather stations in our blog, but none before had this "pagoda" design or used this messaging protocol. That's why we are writing a new post. The aim of this "low cost" weather station is to build it with materials as basic as possible

Adding series to Yocto-Visualization

By martinm, in Programming and Electronics, november 30,2018.

Customers have asked us several times why Yocto-Visualization offers only 4 data series per graph and whether it is possible to have more.

But in order to do so, you must tell the Yoctopuce module how to manage the dialog with the device. So here are a few examples as a complement to the documentation, to make this task easier.
