Any idea how much longer iq 2+ will be supported before an upgrade has to happen ie have they released an end of support date and not just end of life?
The panel will still be supported through Alarm.com for users with existing systems. The hard date for ending of Alarm.com support would be dictated by cell providers, and I believe 4G is intended to be supported through roughly 2030 at the moment.
If you are referencing support as in new development, there will likely not be much additional firmware. The original IQ Panel had one additional update released after it was discontinued. The IQ Panel 2 had 2.6.2 released shortly before the discontinuation announcement.
