Yes please, enable logging in the myVaillant app setting and sharing the logging id or sending a diagnostic report will help identifying the issue
I’ve made a diagnostic report: 7458def6-0b0d-43d5-9a90-19b9beac4048
here also a diagnostic rapport for the device unavailable error

question concerning flow-card: “set cooling-mode to manual” this activates the cooling mode properly, but my Vaillant App shows an End-Time (3 hours) . Is it possible to activate the cooling mode without “time-out”, without end-time?
