The one point that concerns me about the hub is it losing connections at times. I checked and some reviews on Insteon’s site mention that, too. When it loses connections, do you have to delete and reconnect the device or can a reboot do the job? And you mentioned using a Zigbee plug - so there’s no option on the hub to reboot it directly? Any chance that’s available on a web interface?
Do PLMs have a better reputation of maintaining connections than the hub?
I’ve found some connectivity issues with a few Z-Wave devices, but overall, that’s been solid for me. The issue with them is in our barn. The barn was here when we got here. It was a 1 floor cinder block structure with a tin roof and on a concrete slab (other than the trenches in the slab for pig waste!). We removed the roof, added a layer of cinder blocks around the top, then put trusses on top with a 2nd floor built into the truss. I’m going into detail because, as you can imagine, that 1st floor is just a big concrete box so I’d think signals in it would just bounce around in there and one signal from any device would easily connect with any other device.
My issue is the doors. Imagine a cinder block wall, which is 8-10" thick (most blocks are 8" thick). The doors are on the outside edge of the wall, so, including the studs on the inside of the wall (for drywall and to give us space for wiring and pipes), from the inside, there is a rectangular hole in the wall about 1’ deep, with the door on the outside part of that hole.
I had trouble with the Z-Wave locks in both doors and had to get boosters, just for the doors! I had to make sure I could put them in outlets that had a direct line of sight to the locks. With that in place, they work. (Unless someone is standing right in front of the locks!)
I used to use a Universal Devices ISY-994i. It works, I can’t say bad against it, but there are limits to it that I didn’t like - serious limits to programming that I didn’t like. Also, it did only Insteon, Z-Wave, and IR. When I was doing research for something new, I liked that HA could run on a Pi, I could use multiple versions or stick ZWJS2MQTT on a computer in my barn and control both the house and barn from ONE Pi. Since they’re all on the same electrical service, I’m hoping I can control Z-Wave devices in the barn using my PLM. We’ll see.
