aubess smart switch flaw

the 10v 470uf capacitor keeps swelling in the aubess smart switch causing it to last about 2 months or so. I've changed 3 in three separate switches in the house. I believe it's possibly due to the heat. I have drilled plenty holes in the case of the new one I installed today. I will monitor. I will also replace the capacitor in the damaged faulty one. I'm also not happy with the fact that I can't set a timer for it to come on also it does not work with Alexa. it's a pain in the ass...the remote control of the light works well.
