I have 23 systems that I monitor with Optics and have found that most of the issues with connection are poor wifi connections. If they can be hard wired to a router, there are no issues. I have some that use wifi extenders and many work fine but ultimately when they fail, it is the wifi extender at fault. Optics RE is a godsend for keeping tabs on system performance. Many of my customers are off grid second homes and some often go all winter with no human contact. There have been some firmware bugs but it is easy to upgrade to the latest revision.
