Down Button not working

[saruye]

First of all thanks for this awsome integration :) I have it integrated with home assistant and would have never gotten this to work on my own. Mostly everything is working. I can set it to a height and then the desk is moving up and down. And if I manually use the up button it's also working. But the down button is not. What can I do here? What information can i provide to help or where look myself?

It's working fine here!

What if you try this config? (Of course change it to your credentials on some places):

@MathijsG Thanks for the suggestion! At first I tried with quite an old version which produced the issue I reported here. Then I updated and used a similar config as described here. This gave me a crash during the start which I couldn't figure out. After you posted this I looked at it again and realised I used a wrong board. :/ It's an esp32 but the correct board would have been nodemcu-32s. After I updated it, the crash is gone and it's working with pretty much your configuration. So everything good now :) Closing this ticket.
