The IKEA TRADFRI Shortcut Button E1812 is the little brother of the Ikea TRADFRI E1743 push button.
Both are identical in size. The only differences with the shortcut button are that it only has one button (instead of two) and the button surface can be designed yourself.
For this purpose, several stickers are included in the scope of delivery of the button, which can be glued to the button surface either directly or after they have been painted/designed.
The sticker is then simply stuck onto the button and covered with a transparent cover.
I know the following tips are always somehow annoying and seem unnecessary. But unfortunately, many people who knew "better" have already lost eyes, fingers or other things or injured themselves due to carelessness. In comparison, a data loss is almost not worth mentioning, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Because even the coolest project is not worth an injury or other trouble.

Before you start this article, you should have prepared a Raspberry Pi so that it can be reached via the network and controlled via SSH. Of course, zigbee2mqtt and Node Red should also be installed and configured.

Enable Zigbee2mqtt Dashboard
In my opinion, the easiest way to add new devices to your Zigbee network is to use the zigbee2mqtt dashboard. In case you haven't activated this yet, you will find helpful hints in the article Zigbee - Administration of Zigbee2mqtt via the dashboard.
Register the button at zigbee2mqtt
Before you can evaluate the IKEA TRADFRI shortcut button using NodeRed, you must first integrate it into your Zigbee network.
I have a little more detail on how to integrate devices into your own Zigbee network in the article Zigbee – register devices or sensors and actuators with zigbee2mqtt described. The following two steps summarize this briefly.
To put the IKEA TRADFRI shortcut button into pairing mode, you have to insert the battery and the button on the back
- Briefly press 4x in a row
The LED in the button should then flash and the button should connect to your Zigbee network shortly afterwards.
You can track the status of the connection process in the zigbee2mqtt log.
Log into the NodeRed configuration interface
Before you can edit your NodeRed configuration, you must - if activated - first log into the NodeRed configuration interface.
Import node code
The dashboard node should already be installed and configured so that you can also control your Zigbee device via the NodeRed dashboard or display the values. You can find information about this in the following article.
If you are also over pushbullet If you want to be automatically reminded of a dead battery in your Zigbee button, you should also have the pushbullet node installed. You can find information about this in the following article.
As an alternative you can of course also pushover or E-mail use as a notification. You can find information about this in the following articles.
After that, all you have to do is import the NodeCode linked below into your NodeRed environment. Information on how to import NodeRed code can be found in the article NodeRed - Import and export node code .
As always, you can find the NodeRed code in the Nerdiy Git repository under the following link:
Of course you still have to adapt the code to your button. In order for this to work correctly, you still have to enter the IEEE address or the "friendly name" of your button in the Node Red code.
To do this, open the properties of the marked node and enter your IEEE address in the marked area under "Payload...". How to find out the IEEE address of your Zigbee device is in the article Zigbee – register devices or sensors and actuators with zigbee2mqtt described.
In order for the update function to work via the Node Red Dashboard, you must also enter the address here in the marked area.
At the point marked here you can also adjust the message that is sent as soon as the charge level of the button's battery falls below 20%.
You can of course also use the newly registered Zigbee device via the zigbee2mqtt Dashboard control or read out.
In the following category I have also listed other Zigbee devices which can be controlled or read out with the Node Red code offered there.
More articles on the topic
I have summarized other articles on the subject of Zigbee and zigbee2mqtt in the following category. There you will also find articles on various Zigbee devices and how they look like NodeRed can be controlled.
Have fun with the project
I hope everything worked as described for you. If not or you have questions or suggestions please let me know in the comments. I will then add this to the article if necessary.
Ideas for new projects are also always welcome 🙂 .
P.S. Many of these projects - especially the hardware projects - cost a lot of time and money. Of course I do it because I enjoy it, but if you think it's cool that I share the info about it with you, I'd appreciate a small donation to the coffee fund 🙂 .
unfortunately the pairing doesn't work for me. Pressing the pairing button 4 times for no reaction. the red led doesn't flash and Zigbee2MQtt doesn't respond either.
Does anyone have any tips?
that's actually how it should work. Did it exactly like this before. 🙂
Check whether your battery is still full enough and that you have inserted it correctly. 🙂
the pairing worked 🙂
I read in another forum that you have to press 4x within 1.5 seconds. Then it worked.
I was probably too slow :-0
Great, I'm glad it worked. 🙂
