I've been setting up recordings remotely via myhumax.net and the iOS app since I got my FVP-4000T a couple of days ago. It's mostly working fine but there are some niggles:
1. I'm able to set TV programmes to record but at the moment it appears that series link recording is not supported via remote scheduling, only individual episodes.
2. There doesn't seem to be a way to remotely delete a scheduled recording. On myhumax.net the "Delete" tickboxes next to each scheduled item on the "My Schedule" web page cannot be ticked and there is no delete option in the iOS app. (The iOS app is called "HUMAX TV Guide" in the App Store)
3. Yesterday I noticed that a scheduled recording for a programme called "Weather for the Week Ahead" on BBC One HD had appeared on my "My Schedule" myhumax.net page without me choosing to record it. The date & time for that programme are in the past (October 9th 23:55-00:00). When I click on it I get an error message saying "Incorrect Device". Also, because of point 2 above I can't delete it. Maybe I'll have to wait until October 10th 2017...
I've contacted Humax support but there has been no reply yet. [Edit: coincidentally(?), 10 minutes after posting this I received a reply from them: "We are aware of some problems with the features of the remote recording app, we are currently working on these and will be releasing an update soon."]
