I'm looking for a master controller for my ROI-E720 and I want to avoid paying the $300-$400 asking price (depending on where you look) for the Grower's Choice unit. The light uses the 1-10v standard and I'd like the sunrise/sunset feature. I found this one: https://sunplix.com/product/grow-light-master-controller/ and I would like to know if this would be compatible with my lighting system.

Anyone with some first hand knowledge of the Sunplix Controller?

Anyone know of a cost-effective alternative? It seems like the Grower's Choice asking price is excessive when compared to some of the other brands.
