Konnected Pro Alarm Board - Any cheaper/viable alternatives?

Hardware
1

I’ve been searching for ways to update/upgrade my Home Security system (ADT SafeWatch Pro 3000) and while there are few alternatives, it seems the front runner is the Konnected Pro with Ethernet. There are others, but they appear a bit dated (websites too), and their customer support is ‘borderline’ (based on multiple reviews). The only ‘issue’ for now is that the Konnected Pro commands a rather steep price (~$230). And I’m sure there are additional ‘add-ons’ one needs to get further down the line.

I would like to hear from community members who have adopted such board, their experience (positive/negative), and viable alternatives if any. Naturally, one has to balance performance vs. time to setup vs. cost …

Based on some Googling, that’s a Honeywell Vista system.

That being the case, you’d want an AlarmDecoder.

Konnected piggybacks to your panel with non-isloated ESP GPIOs connected to your sensor lines! AlarmDecoder just communicates with your panel directly.
