Zwave slow

Why All my Zwave are very slow since one mounth

You’ll have to provide some more infomation. Which Homey do you use? Homey Cloud (Bridge), Homey Pro 2016-2019, Homey Pro 2023-2026? Which software version? Which Z-Wave devices do you have? And are all devices slow, or only specific brands?

I have the same, started maybe about a month ago TX errors across the nodes now range from 30% to 100% before whatever the updates was most nodes were 0% maybe some up to 10% etc

An homey update for firmware update has destoyed the mesh by the looks of it.

No amount of route updates seems to make any difference.
