A classic in home automation is to add different sensors, in today's post we are going to see some examples of how with Home Assistant and pressure sensors we can do very curious things. Sensors that we can put on the bed, on a carpet, sofa…
Post to continue completing our home automation system, Or it can be interesting if you intend to set up a weather station… Today it's time for a rain gauge, at the end of the document we will know how to measure the volume of rain and be able to visualize it in Home Assistant, or perform some automation…
Despite the title… If you are a person who usually teleworks and you want to put a device that with different lights informs the rest of the family members of your status, for example red light if you are in a meeting or call, orange if you're composing an email, Free Green…
And Monday arrived, and with him, New Podcast; today in A Podcast for IT we have a super interesting talk about the IoT world. We will understand what IoT is, quite a lot of what it covers at the business level and of course at the domestic level.
Another possibility that we can give Home Assistant is to install smoke detectors, These are wireless, powered by a small battery and communicate any notification by radio frequency., There are many types and quite cheap, For just €5 you can make sure that nothing burns in your home or office! This is how cheap we protect ourselves, and in the end we will see how to alert with Telegram in case there is smoke.
If we want to place motion sensors and perform actions based on detecting movements, we will be able to use some cheap Chinese IR sensors that are powered by a couple of batteries, they are small and disguised… In this document we will see how to add them in Home Assistant and how to configure some actions, For example, If we're not at home, Well, send us a Telegram message notifying us of a movement, or at a certain time turn on some LEDs to illuminate.
Start the march! The first step in my case (after having Home Assistant installed), will centralize and receive all radio frequency signals with the fabulous Sonoff Bridge RF; and then send the sensor data to the MQTT Broker that we will mount in Home Assistant. That is, the Sonoff Bridge in this case will listen by RF and transmit by Wifi to the Hassio any data that interests us.
Imagine the thousand possibilities that having an optical fingerprint sensor connected to a Raspberry Pi gives us, We will be able to capture and identify the information of the fingerprints that interest us and take actions based on it. In my particular case I put it at the entrance to the house, If you find my footprint or those of my family, because it opens the door without the need for keys!
If you feel like measuring wind speed using a Raspberry Pi, This is your document! You may be thinking of setting up a weather station and this is an important issue, TRUE? We will use a script and a specific anemometer and super fast we will have it set up. Apart from, As you already know me, I will export the measurements to a MySQL database and then visualize it with Grafana!
If we want to analyze some type of gas with a Raspberry Pi, we can make it very simple with MQ sensors, we will only need to know in any case which sensor to obtain depending on the gases to be analyzed and that's it, We will see in this post how to connect it and get the values. As usual, at the end we will save the data obtained in a MySQL database to visualize it from Grafana!
