Looking for a good replacement for an old Iris Centralite 3510-L

I have an old Iris Centralite 3510-L, running on old original firmware, its all but dead, acting weird, both zigbee and z-wave keep popping in and out of the network, mostly out.
Anyway, looking for some recommendations on anything better, don’t care if zigbee or z-wave. I would like to have simple switchable plugs but also a few metered plugs like the 3510.
Thanks in advance!
