I had a scary experience with my MXM linked to EcoTech Marine Vortech MP40 QD and Vectra S2. I was changing my Apex WiFi configuration, which followed by a restart. After the restart everything in Apex Fusion looked as usual, it was reporting that both devices were running as previously configured. Luckily I was near the aquarium to hear that the return line started to gurgle. To my surprise both devices were running at minimum power. They were not completely off, but what is most important, they were not running the fallback profile neither (fallback was setup to match the Apex configuration).
Since the incident I was not able to control them via MXM, so I had to unlink them.
