Graph Feature Mod Suggestion

Would be a useful feature to be able to select the start/stop date/time for the x-axis. It currently is set for a fixed start date of several weeks in the past. Be better if we could select the start date to be say 24 hours ago or even 1 hour ago so the plotted data would have more time resolution.

Would also be more useful if the Lochinvar Boiler and this app could be synced to real (NTP) time. Right now time seems to be displayed based on Lochinvar Boiler time which is losing more than 30 minutes each day.

Awful

App crashes every time I hit “About.” It also doesn’t display any of the sensors like it should. It worked for a while and then all of a sudden stopped. All I get now is basic run state.

Very disappointing

The app only works (for me) to check status of the boilers. I had two faulted out recently on LWCO (test not reset). Unable to do any about it. The graphs are useless and seem to pick arbitrary dates and parameters. They appear non-adjustable. Having data from 5 weeks ago doesn’t help much. The ranges are really too wide to be of use. A example is on a temperature graph it shows a range of -40F to 240F over a two week period. Lochinvar can do better. The boilers are fine units and this app is far below that standard. It’s obviously a low priority for them to improve this.

Does not seem to work on Apple iOS

I have follow instructions and videos on how to register and link to app.
Got boiler connected via WiFi and it’s showing solid connection.
Registered boiler .
Issue is that once logged into app I don’t see any current readings at all as if the unit is not connected.
Tried to re-register unit but that failed.
There is no way to log into web based site account to delete and re-register to see if that corrects issue.

Have read that the app does not work well for Apple devices.

Just disappointing that I cannot get this online for remote diagnostics.
