Anubis, Great God and Watchful One, I ask for your permission to access Watchtower. Please hear my voice (text), and if it is your will, grant me the wisdom and protection and access I seek. I bring you this offering in gratitude for your presence.
It worked this time! 
(the dashboard wasn't working with manual install, it now works after HPM install, too).
I made a long, complicated post but deleted it because I determined a simple cause of the problem, which is still outstanding.
In Watchtower 4.1 I have a single-attribute panel with two switches. I have userscript that modifies the data thus
$config.data.datasets[0].data.forEach(pt => pt.y = pt.y > 50 ? 1 : 0);
along with some other stuff modifying the scales and tooltip to present as binary on/off like I want. It works and looks as expected when I update the tile.
However, when a refresh occurs and new data is read in, the userscript doesn't get executed, so the data no longer fits the rest of the setup and it's borked.
I assume there is some hook or setting that I've missed, or this sort of manipulation by userscript would never work on an ongoing basis. Help?
I believe you found a bug, I'll take a look when I get a bit of time. Thank you for putting effort in pinpointing this issue.
Bug report with beta version 2.4.4.124 on a C-8 Pro: A dashboard that just outputs all available hub parameters (stock choice in WT) now generates this error: "can't access property "status", e is null". The dashboard worked with beta 2.4.4.123, and still works on a C-8 with 2.4.3.177.
I would probably wait until the classic dashboard bug is fixed before posting here about it. This is a beta issue that has been a well reported on the beta forum
Hmmm …. Not sure we’re talking about the same “dashboard“. I’m not talking about Hubitat dashboards, I’m talking about Watchtower dashboards.
It's the same bug; it affected more than just the HE dashboards - it seems to be fixed in beta .125
Nope — I just updated to .125 and ran my formerly working Watchtower hub information dashboard and got this:
“null is not an object (evaluating 'e.status')“
I updated my C-7 to .125 and the Hub Information WT tile works fine. Is this maybe a C-8 Pro only issue that I cannot reproduce?
I recreated the entire hub information dashboard that I was using, and all is OK. So there must’ve been some corruption somewhere.
