the udpate for the single tracker multi RS has brought a small bug in the VRM.
Around the time I made the update, I switched my (single) multi RS to phase 2. not that it was exactly needed, but well, I was connected to phase 2 so I put him on phase 2.
since then the internal power relais alway show as open, even when power is drawn from the line. I guess that's self explaining, but the relay in reality is properly closed and all is working well - it's just visualisation on VRM that doesn't work.
