I ran into an interesting data point that I would like to see if Beestat could solve. I also would love to expose this to Home Assistant but I wanted to start here.
I have discovered massive impact to my furnace filter being dirty. Go figure. Now I do have a regular reminder to replace it got me thinking.
I was finding 4 hours to heat just two degrees C. This was with a 3 month old filter. After replacing with roughly same outdoor temp this changed to 1 hour.
So these Temperature Profiles charts for efficiency must be impacted by this. I would like you could track this data in some fashion over time and alert on it. A tipping point should exist.
I would like to see it baseline the system for the “best” Temperature Profiles. Any deviation from that could be displayed based on say the last weeks trend. This could be represented as a percentage from optimal.
It would also detect this being caused by other items such as mechanical issues.
Appreciate the feedback! The good news is that the temperature profiles are tracked over time. I store a new one every single week for all users. Bad news is that the data isn’t readily accessible in the app just yet, so it’s tricky to actually access that info.
I do like the idea of using the data to look for issues, though. You’re right that those trends could generally be used to identify potential problems.
Another vote for this, and it does not need to look at long term trends.
For my case I had an interment failure on flame detection in my gas furnace. It would be normal most of the time but every once in a while the furnace would fail ignition and not be putting out heat. The ecobee would just go on as normal running the fan, step up to stage 2 after 15min, and have stage 2 run times of 2-6 hours and shutoff when the sun came up and heated the house up that little bit it needed (0.5 degree heat differential).
In this case if the runtime goes way beyond the historic degree per hour then it could send a failure warning, or a system not keeping up with demand notification as the inside temp continues to drop.
In my case it was an intermittent issue that got worse over time but took 4-5 months to notice and only when it started to get much colder at night. Then once I determined the issue and fixed it had to wait 1 year for the bad data to fully fall out of the system to have the graphs and analysis be accurate again.
Not to my knowledge. On the 3 Lite I have high/low temp and humidity alerts but that is it. Neither one would be triggered in this situation.
Edit: Checked the Ecobee website and it has an option listed that is not listed in my app. I have never seen on the thermostat itself either, so either it does not exist on my unit, or is newer than the SW version when I was having issues 3 years ago.
Enable Heating/Cooling Alerts: Select ‘No’ to disable alerts for heat/cool error conditions. If disabled, alerts indicating that the system failed to heat or cool will not be generated.
