Decent overpriced monitor, needs more...
Overall the unit operates fine and performs the advertised functions properly. I generally do not have issues with signal but have had a few loss of signal alerts displayed, but never when I was using the monitor. Likely due to wireless/cell interference. I'm pretty happy not having to go outside to check on the generator status but the graphs display could be improved to include more information. It would be nice if there was the ability to display the current watts/amps in use when running on generator.

Installs Easily & Work's Great!
I have mine mounted on wall in kitchen, & no longer have to go outside to check my Generac's status. Can also start it up (& use Transfer Switch) from inside, check History, etc. Make's my Generac setup complete!

Great Convenience if it doesn't FAIL.
2 hours after the programmed weekly "power on" test was completed, I lost the "radio link". I had to reinitiate the "default" channel (initial setup). This required going outside and removing the electrical power from the generator and removing the circuit breaker/remote link connector. The manual stated that would only be required if the "default" channel was noisy. Reinitializing the default channel was successful. Selecting another channel was NOT required.
According to the poorly written manual the default channel should have automatically reset itself once the "noise" was removed. Since the reset, operations have been normal.

It's just
The "user interface" on this device is from the 1980's. It does work but is limited in functionality. There is an amber LED that indicates that the wireless link is working, it would be much more intuitive if that light was green and also indicated that the generator was "ready to go". Generac has very limited remote control capabilities (this device alone, I believe). No Internet capabilities that I am aware of.
