How to control Gladys with NFC tags
How can we interact with Gladys without opening Gladys web app ? With NFC tags ! NFC tags can be sticked where we want, and by just touching them with our phone, we can trigger events and scenario in Gladys.
We’ll see in this tutorial how to configure NFC tags to use them with Gladys.
- A few NFC tags like those.
- An Android NFC compatible smartphone ( unfortunately this doesn’t work on an iPhone )
Tasker is a great app that allows you execute actions based on triggers and conditions using any sensors of your phone. In this tutorial, we are going to use this app to make HTTP requests on Gladys when a NFC tag is touched by your phone. The app cost something like 2$99, but compared to what the app does, that’s a great price.
- Install first Tasker
- Go to preferences, on the
Misctab, then tick
Allow External Access(So that the Trigger app we’ll use next will be able to execute Tasker tasks)
Create a task in Tasker
We are now going to create a task in Tasker.
How to tell Gladys you are going to sleep ?
I have a simple scenario I use everyday: I have a NFC tag sticked on my nightstand, and when I’m going to sleep, I simply put my phone on it to tell Gladys it’s sleep time. Then Gladys execute my “Going to Sleep” scenario (She turns off the lights, … ).
To create this task :

taskstab in Tasker, and click on
+at the bottom of the screen to create a new task. Give it a name, for example here

Pathfield with the API route you want to call in Gladys. Here we want to create a Gladys event, so the route will simply be :

Note: If this task gives you an error in Gladys saying that this
EventType does not exist, it means that you don’t have the last eventType list. You can update this list by going to the
Parameters of Gladys, and by clicking on

Trigger is a free Android app that allows you to execute action when an NFC tag is detected by your phone. We’ll use this app to start the Tasker task we created before when a specific NFC tag is detected.

+button, then select
- You can now define restrictions based on the hour of the day and your Wi-Fi connexion. Select what’s the best for you and click on

Thanks to NFC, possibilities are endless. Any zone of your house can become a physical trigger to a Gladys scenario with a simple NFC tag.
To tell you a little story on this, I have a NFC tag on the wall of my flat. When my phone touch it, it starts the
romantic mode : Lights goes red, and a little jazzy music is played in the living room.
And you, how are you using NFC at home ?
