This issue with wormhole https re-direct has not been fixed. The issue was at datplicitys end not correctly presenting itsself to the emonpi as a https proxy. They have now fixed this issue and wormhole works great again 
Note: Dataplicity has implementing a hotfix to fix this issue. If there are are issues reporting over the weekend they may need to regress the fix while issues are investigated but it looks good at the moment. If it dosent work for you yet please give dataplicity some time to fix this. The fix is coming!
I’ve been working with Dataplicity today for a number of hours to resolve this, they have been really great. Please support them if you can by considering taking out a $3/month paid plan to have multiple device access.
I’ve also tested setting up dataplicity using our off-the-shelf emonSD-26Oct17. It works great. Really simple setup using the setups outlined by @Radoslav_dataplicity on this thread:
