User Reviews

Most reviews report reliability and usability issues: crashes, a landscape lock, registration/ pairing problems, and unreliable graphs. While some users find the app useful for boiler status and remote capabilities, the frequent defects significantly hinder remote diagnostics and day-to-day monitoring.

Pros

Useful for monitoring boiler status and readings.
Remote access and programming capabilities for Lochinvar boilers.
Good functionality and ease of use when the app works.

Cons

Frequent crashes and instability (e.g., crashes on About, sensor display failures).
Landscape orientation lock issues that force landscape and hinder use.
Registration, login, and device pairing problems that prevent adding/removing boilers.
Unreliable graphs and data visualization (non-adjustable ranges, outdated data, or no data).
Connectivity and data reporting inconsistencies between local and remote access (offline status not reported).

Recent reviews

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.

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.

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.
