Agreed. I have Lutron Caseta Clear Connect, Hue, Z wave and Zigbee devices in my home. Of these four, I find the Lutron and Zigbee devices to be more user friendly.
The key to a stable Zigbee network is to have a few inexpensive Zigbee smart plugs around the house. They act as Zigbee repeaters.
I have heard that Securify Peanut and Innr plugs are not great repeaters. In order to make the design highly compact, I think they may have skimped on some components.
Although I have not tried them, the Ikea Tradfri plugs are often recommended.
I have used the Centralite smartplugs and they seem to work well. Centralite used to make the plugs for Iris and for Smartthings; now they sell under their own brand. I have a plug in the kitchen, a plug in the garage, and a plug in the basement. That has kept my Zigbee network stable.
If you are looking for a Zigbee repeater, be sure you do not end up with a WiFI or Z-wave device as many of the devices look nearly identical.
