Hi. Is it possible to replace the shipped power supply, 2,1A with a 2,4A power supply? Or is this bad for the Homey?

That’s not a problem. 2.1A or 2.4A only means that the adapter can deliver it, not that it does.  
Voltage is also important. 5V.  
But is this for the Homey Pro 2023?  
There, the adapter did not deliver enough voltage.  
The replacement adapter for Homey Pro 2023 is 5,2V and 2,1A.  
Homey Pro 23

In that case you have a Homey Pro (Early 2023)

> USB Power Supplies and cables This test is performed due to the email send by Athom after the first shipment of the new Homey’s The first shipment has received a power adapter which unfortunately makes Homey Pro’s CPU underclock. [Read the e-mail here »](https://mailchi.mp/217770f9b300/homey-pros-power-adapter) But also for users that have to replace their adapter or cable in the future. And I have read a lot of nonsense on Slack and on social media around it, so let’s see if we can clarify. TL:DR: Test it and if you can measure it. Bigger or newer …
