We're starting to go on more and more long trips. This might be a good solution to ensure the SWG is doing its thing and that pH isn't going crazy. We have family nearby who can come by if anything needs to be done, but they are in the busy career and little kid stage of life, so I would rather not ask them if it's not necessary.
I generally get the pH on the low side and run the SWG a little hot, and we come home to a pretty pool with pH on the high side. But it would be nice to see the numbers remotely.
