Thank you @bonamin. I did get this working in HA with REST commands without using Blynk. I found a post where someone was using https calls to control their pumps so tried it in HA and it’s working. It would be a lot nicer if Aquascape would provide api that could be used for an integration but …
I’ll post the calls here in case someone else is going down the same rabbit hole I did. (The forum only permits me to post two commands. If anyone would like all of them just contact me.)
