This article describes a way to create and manage multiple very simple temperature and humidity sensors based on Arduino MKR1000, and being able to send their information to Home Assistant, using MQTT.

Why do you use such an expensive device? I’m using a bunch of ESP8266/ESP32s for the same job…

Absolutely. It’s just that the MKR1000 is very versatile, and I use it for many different thing. But you are totally right, if you want a really cheap sensor, there are better ways.

No offense! I was just wondering if there is any special case why you took this board!

Hi,

Did i miss something or is there no mqtt broker mentionned in your project description ?

Hi, no you’re right. At this time, Home Assistant was including a MQTT server out of the box. I think this functionality has been deprecated (Embedded MQTT stopped working on ver 112), so you may need to install a Mosquito plug-in now.
