Sending values with communication modules

By mvuilleu, in New stuff, september 15,2023.

Yoctopuce serial communication modules such as Yocto-RS485-V2 and Yocto-I2C are capable of autonomously executing small communication protocols, for example to interrogate sensors. We were recently asked whether it was possible to use a value received from a sensor in a message sent later. As is often the case, the answer is: yes, it's now possible...

Rotary knobs with quadrature encoder

By mvuilleu, in New stuff, august 25,2023.

The Yocto-Knob and Yocto-MaxiDisplay variants have analog inputs for connecting interface buttons: pushbuttons, rotary knobs. However, there was one type of button that was not supported: infinite rotary buttons with quadrature encoder. This limitation has now been lifted.

Taking back control of a YoctoHub-GSM-4G by SMS

By mvuilleu, in New stuff and Misc, august 04,2023.

To take measures in the middle of nowhere and to transmit them to a server, the simplest solution is usually to use a low-power 4G network such as LTE-M or NB-IoT to send them periodically to a server. For example, you could use a YoctoHub-GSM-4G configured to perform HTTP callbacks to a PHP server using VirtualHub for Web. But what if one day the hub stops connecting to the server?

New: The Yocto-LatchingRelay

By martinm, in New stuff, june 09,2023.

This week, we present the Yocto-LatchingRelay. Officially, it's a new product. Unofficially, it replaces the Yocto-LatchedRelay, which we wanted to get rid of for a long time.

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.
