There is a bug in the smartthings integration towards bosch home connect. Turning on/off the diswasher works fine. Also selecting the program works fine. The issue has
been reported by several members here as well: Home Connect integration does not work - #14 by Koen_De_Jaeger .
The setStartstop api POST call gives no error message but doesn’t start the dishwasher program. Same experience in Samsung account , where the setStartstop command doesn’t even appear in the event log after triggering it.
I tried contacting Samsung but you’re redirected back and forth between the support centers and in the end it doesn’t reach the developer that needs to fix this simple bug. I wonder in which github repo maybe we could make an issue for this. I also send a msg to bosch and samsung through facebook support in the hopes it would reach the right place.
