Embedding Yocto-Visualization in a TypeScript WebApp

By mvuilleu, in Internet of Things and Programming, january 02,2026.

A few weeks ago, we showed you how to create a small WebApp for remote control of a heater using a simple HTML file and a few dozen lines of TypeScript code, thanks to VirtualHub for Web. This week, we'll take it one step further and enhance it by adding a graph showing the history of measured temperatures.

A control WebApp with VirtualHub for Web

Yoctopuce products enable you - among other things - to remotely control a device via the Internet. What's special about the Yoctopuce solution is that it's not based on a proprietary infrastructure, which could shut down any day and render all these systems inoperable, as has already happened far too often. Yoctopuce offers remote control tools which you are free to install on the host of your choice, and which you can move to another host in a few years' time if need be...

Monitoring a solar thermal system

If you've ever discussed photovoltaic solar panels with a proud owner, they will certainly have proudly shown you on their cell phone how much electricity they produce every day. With thermal solar panels, on the other hand, remote control is less widespread, as control systems are generally more primitive. So let's take a look at how you can add a simple monitoring system to your domestic water heating system, which could maybe save you a few hundred kWh a year...

Switching the Home Assistant extension to Async

By seb, in Internet of Things and Programming, may 31,2025.

A few weeks ago, we announced our new Typed Python programming library, which offers an asynchronous API in addition to the "traditional" one. This week, we'll take a look at how to use these asynchronous functions by updating the Home Assistant integration we described in this post.

Controlling a relay from Home Assistant

By seb, in Internet of Things, february 16,2025.

Some time ago, we looked at how to build a smart extension cord and how to use it to monitor the consumption of an electrical appliance with Home Assistant. We're going to enhance this Home Assistant integration by adding the ability to switch this extension cord from Home Assistant.
