Love the sump setup, and also oooooof on the sump setup. Same thoughts for mission critical systems and third-party monitoring (combination of neighbours and a service through wifi with a GSM backup), and we have an older DSC panel that I popped an Envisalink into.
The hubitat had promise, but it’s reliability is a deal-killer for me, and DB data corruption happens too frequently if it loses power. Indigo Domo is a fantastic piece of software that has served me really well, but nothing on the roadmap for zigbee (there are third party bridges to other systems), and a reliance on MacOS which is being tested (as in strained) as Apple removes Python as a default with a point release.
