myVAILLANT Pro Service

Just downloaded this, I’m a Vaillant advanced installer and am unable to log in. Keeps saying password is incorrect but this definitely isn’t the case.

Really helpful app. The following improvements would help: - more recent data. It seems there is a multi-minutes gap before an event is displayed on the app. - occasional graph crash bug - the graph should allow to zoom in/out. - outdoors temperature is not available with VR70 with wireless controls - modulation rate should be put in contrast with heat source modulation range capability

I have put my correct email address and password in, it comes up saying incorrect - I had the same issue with ServiceASSIST and that was never resolved - come on Webdev, improve your bug fixing!!
