Triggering an IKEA smart plug from IKEA humidity sensor

Hi everyone! This is my first post, so hello to you all.

I’m trying to automate a dehumidifier in my basement so that it switches on automatically when the humidity reaches a certain level.

My setup consists of:

  • IKEA DIRIGERA hub
  • IKEA TIMMERFLOTTE humidity sensor
  • IKEA smart plug
  • Dehumidifier connected to the smart plug

I couldn’t find a way in the IKEA Home Smart app to trigger the smart plug based on a humidity threshold, so I tried creating the automation in Google Home instead.

Everything appears to be configured correctly in Google Home, and I can see the humidity sensor and the smart plug. However, when the humidity exceeds the threshold, the smart plug doesn’t switch on.

If I manually press the Run/Play button for the automation in Google Home, the smart plug activates and the dehumidifier starts, so I know the plug itself is working.

Has anyone managed to get this setup working with the IKEA humidity sensor? Is there something I’m missing, or is this a current limitation of Google Home or the IKEA sensor?

Any advice would be greatly appreciated. Thanks!

Hi, welcome to the forum!

As my fellow HA user mentioned + in case you didn’t know and still haven’t grasped: Home Assistant is another smart home platform which, in contrary to that search engine company:

  • respects your privacy
  • non proprietary
  • is open, which makes it possible to connect to and control almost everything
  • and many other differences

Additionally: that smart plug can be controlled, based on the humidity by home assistant but that would require running home assistant on some kind of system and a way to connect these devices to it.
If interested, do a search on dirigera home assistant and TBH I don’t know what would be the best way since I connect IKEA devices ‘directly’ to HA, without an additional hub.
By ‘directly’, I implied that HA becomes the hub and you just need a way to communicate between HA and your end devices; I’m doing this with a Zigbee coordinator.

TBC: there are multiple ways, depending on the communication protocol that your end devices use.

Sorry if I’m on totally wrong forum I can switch out. I’m just getting started with Home automation.

If you are just starting my suggestion would be to skip setting anything up in Google Home, go straight for Home Assistant. There’s plenty of documentation on how to start on home-assistant.io
