Yes I have used the Carrier Infinity system, But a older couple a customer for years bought a new townhome and it is a new Armstrong system and i was trying to help them find something like the old pc8900 but that never worked that well.

Check with wright/hennepin electric (whe.org)
I have several customers who are monitored by them. they can do temperature, water, fire, burglar whatever. and they serve a wide area around the TCs and nationally for others.
For a relatively small monthly fee and they supply the monitor equipment and place a callout for service. They can direct you otherwise if needed.
I also have seen a few internet capable standalone stats through Minvalco but never used them.
I monitor in our office a few places as well but they are a wee bit more involved than a home.
I don't think anyone can consider this a "monitoring system", but I have sold several of the Honeywell S483B1002 Winter Watchman (Honeywell retail consumer # CW200A1032) to customers. It's a line voltage thermostat that plugs into a receptacle. You turn a lamp on and plug it into the Watchman. Then put the lamp in a window where neighbors can see it. It can be set from 30 - 60 deg. F. I carry one on the truck, and have even loaned one to good customers who are going on vacation in the winter.
I own a Armstrong Air Ultra 80 oil furnace LUF80C112/125D20-1
I want to replace my very old 8 SEER 3.5 ton outdoor compressor.
My game plan...
Replace the compressor with a 3 ton unit (I find that the current unit simply is not on that much in the summer (we do not put the temp. lower than 76 in hot weather) and we are usually very comfortable.
I plan to buy a 3 ton Amana 18 SEER compressor (ASX18 0361A) and want to be sure I get the right coil to match.
Looks like uncased coils CAUF3642D6A, CAUF4860C6A or CAUF4860D6A should match. (actual width might be an issue)
The SEER ratings are based on a variable speed fan. My Armstrong Unit has a single speed direct drive fan with time delay.
The folks at Armstrong gave me the part numbers for their 18 SEER unit and said I would need an Expansion Valve (part A4TXV0TTXV) to go with the coil.
The Armstrong rep also said my fan is rated for 5 tons (seemed high to me)
Can this set up work?
What does the Expansion Value do and do I need it?
Is the ASX 18 0361A a good buy for about $2,500?
Please note - I am not trying to do this on my own, just trying to get the best info.
