See there in lies the one issue I do have with GHL. For the life of me I can’t make connections outside of the house 100% of the time. Inside on the hotspot of the doser it connects very well. I haven’t really tried to troubleshoot it and I’m sure with effort I can make it’s connections better and more reliable but until I figure out that part I’ll be keeping my apex doing what it does since in a pinch I’ve had to open apex and shut stuff off and there’s no delay where I’m terrified that in the moment the GHL won’t connect.
If I get the connection to WiFi stable you can dose anything you want whenever you want as all the dosing heads are able to be controlled remotely but for me I’m running the KH director in control mode so if there’s a drop or rise in alk from the target it adjusts the dosing of alkalinity accordingly which is pretty sweet.
