ZWave JS devices keep becoming unavailable

I think I’ve done a good job rebuilding my network. I brought over the four closest switches then let them sit for a day before trying to automate them. A few days later I did the next closest four and let them sit, and then I did another batch a few days later. I still have another four or five devices to add, but they are the furthest from the hub. Everything I have is mains powered.

I should add I’m coming from Hubitat, so this is my first time using an external stick.

After posting, I stumbled across this post. Automate ZwaveJS Ping Dead Nodes? - #5 by Prodigyplace

Would you think there is a possibility this is related?
