The replies on this reddit post have some more useful info comparing Inovelli and HomeSeer.
In a nutshell-
HomeSeer lets you individually control LEDs. Inovelli doesn’t, but Inovelli has more colors and flash patterns. HomeSeer’s LEDs are harder to see from farther away, so this is a matter of taste.
Inovelli lets you disable the internal relay or make it remote control only (smart bulb mode). HomeSeer doesn’t support this.
Inovelli works without neutral. HomeSeer switches and dimmers REQUIRE neutral.
Inovelli has energy usage monitoring (if you use neutral). HomeSeer doesn’t (although knowing how many KWh a LED uses is of debatable usefulness).
Inovelli supports 3way with smart addon switches or dumb 3way switches. HomeSeer only supports smart addon switches.
Inovelli allows setting config parameters locally (with the config button and multiple taps). HomeSeer only allows parameters to be set from Z-Wave.
Inovelli costs $37 / $40 (switch / dimmer). HomeSeer costs $45-$50 (switch / dimmer).
Both companies have active communities.
You’re going to get a great product either way IMHO.
