[E Cascade]

I have a CYV about 5 yo. I am at my villa early Nov-. end of Mar each year. This past summer my AC compressor topped working when I discovered it by a friend stopping by and finding that the house temp was higher than setting by about 5 degrees. I flew down and in about 4 days all was corrected and a new compressor was installed.

If I had an Ecobee installed I would have had a message on my smart cell, but as I understand the way they function is that it detects the dysfunction thru the wifi system. Currently, I have my internet/wifi on seasonal when I am not there and it decreases my Comcast bill significantly.

Questions:
1. How can I have info about the temp in my villa whenever I need it?
2. Can I just get a temp monitor, like one for an RV or a green house, that will give me that info using my cell phone, but not need wifi?
3. Does the Ecobee require the wifi to be on all the time or can I still have it put on the seasonal use and get the seasonal discount?
4. I've seen online some units from "NectoRV" or "Govee" that monitor the temp and humidity.

What I need is the info, if something is amiss while I am away. No matter how I get that info, I'd have to fly in to have the repair work done and that is no problem. It's trying to find the advantages of the Ecobee vs the other kind of product that does not raise or lower the temps, but rather just tells me of a problem.

Please know God gave me no technical, electrical, or mechanical abilities, but rather He gave me other talents. So I am grateful for any and all of your suggestions to help me figure out what changes I need to make when I arrive back down there in a week or so.
Thanks for your help. Have a great weekend coming up.
