I’m looking to install an alarm on my hose, and was looking at 2Gig, but the problem there is there is no option that I can find for local integration with HA. IT seems it MAY be possible through alarm.com, but that would require HA going out to the web and getting its info there - that requires internet connection. I want it to function even if there is no internet connection. I then looked at Elk, but that’s way over powered and over priced for what I’m looking for as I don’t need any of it’s add-on capabilities, like Automation.
Enter DSC - they’re reasonably priced, they have a serial interface (IT-100) and I found the EnvisaLink, which appears to give it 2Gig/Alarm.com type capabilities (alerts without all-out central station monitoring).
I found the info about AlarmDecoder, but does one need to use THEIR hardware to make it work? Or would theDSC IT-100 serial interface work just as well as their Serial interface?
I’ve read some posts about EnvisaLink working and being supported, however, it’s not listed on the ‘components’ page.
Since EnvisaLink seems to be an Alarm.com like service would HA be able to interface with it direct and function with or without an internet connection (and is it really fully supported, just forgotten about on the ‘components’ page)?
Any other thoughts?
