Occasionally my Comcast WiFi modem will have a problem. Either there is no internet connectivity, or it is painfully slow. Rebooting the modem usually clears it up. The forces the modem to make a new connection.

Next time you are having problems reaching your thermostat, call Spectrum and ask them to do a diagnostic check on the modem. They should be able to diagnose the issue and send a reboot if necessary.

The fact that it happens on the hour is a little suspicious, unless it stores up all errors and gives just one update on the hour.

What was the content of the message?

Sometimes low tech is a better way. I monitor a lot of equipment at my workplace. I have wireless transmitters reporting to a gateway that logs data and organizes email and test message alarm notifications on a remote server. It is nice to get the detailed info, but when there is a gateway disconnect, I am vulnerable. The system does notify me that there is a disconnect and that message is distinct from a known equipment problem. There are thousands of hours of work and hundreds of thousands of dollars of materials at stake. Do i go sleep there instead of at home in my bed? Sometimes I wish I had my old dialer back with wired connections to relays on the equipment that triggered a phone call on an ultra-reliable copper analog line.

This is my round-about way of suggesting inexpensive, low tech solutions for the home. Right now I am monitoring a home in central New York State. It was about zero degrees there this morning. The neighbor across the street saw the red light in the window and checked it out right away. About the same time my sister and I got phone calls and my sister texted him. I am at least 1200 miles away and my sister about 40. We are running both of the following:

If you have neighbors that can keep an eye on the house, consider this old-fashioned device: Honeywell Winter Watchman. People have been using this device for decades.

If telephone service is available, something like the Intermediate FreezeAlarm, FA-I-CCA, Protected Home, A Division of Control Products, Inc (I see indications that this particular model is obsolete and has been replaced by a similar model.)

With the Winter Watchman, sometimes there are problems with having it plugged into a wall outlet, as designed, because of cold drafts. Simply plugging it into an extension cord solves that.

This morning the room that both the devices occupy was, indeed, colder than the thresholds we set. The boiler and entire system was working fine. Kind neighbor bumped the t-stat a little, heard the familiar and comforting relay click and the muffled reassuring sound of the burner fire up. Believe me they are a comforting set of sounds in the winter, able to be heard in a quiet house, but not intrusive for me. The temperature differential between the room with the t-stat and the one that the alarms occupy apparently grows with lower temperatures. All in all, it was a good test of the systems. We've made minor adjustments and are happy.

Note that I can call in and get the actual temperature from the FA-I-CCA. I just checked and it is 56 F in that room.

Weedmeister: Honeywell checks every hour and reports to me via email if there is a problem. I assume in my case the internet connection failed for between 3 and 5 hours, so there were 4 failures. Mike: Remotely rebooting the modem is not an option for me, but I guess the cable company did it. Ionized: I like your solution. When my home was wired, the GC ran power, cable, and a POTS telephone wire through the trench. There is a buried telephone line crossing my property, with an olive green connection box on a short pole a couple of hundred feet away from there the end of the line to the house is, so I could sign up for telephone service and connect to that line, but is it worth it? Maybe YES, for peace of mind. Unfortunately, there are no neighbors or any road within sight of my house. I could pay someone to be a caretaker and have him check if I detect a connection failure, but there will be a lot of false alarms!

From your description, this is a telecommunication problem, not a thermostat problem. If the messages ended then that suggests the connection was restored.

Over the 18 months I've had Honeywell thermostats, the Honeywell My Connect Comfort site that I interface with has had a few hiccups. Nothing major and never a problem since these are in my primary residence. I really like the Honeywell thermostats and don't consider the rare minor hiccup an issue.

Thermostats are pretty reliable devices that last a long time. It's probably safe to assume that a temporary interruption in remote connectivity doesn't suggest there's a problem.

Next time this happens call Spectrum and ask if they can reach your modem. They are the ones who may be able to resolve it remotely.
