I thought I would ping the hive mind here, as I am at a loss. So I am helping a friend get ST up and running in her home, as she like what I have done with mine. He goals are
- smart dead bolts front and back
- control over an exterior light where the switch is located in a storage area.
Seems pretty simple right? Well the home is ~120 years old. It was built without electric, I think most of the old gas lines are still in the walls. The walls are lap board and plaster. And I am guessing some of the lairs of paint are lead.
We started with the Hub, 2 of the iris Zigbee/zwave plug-in adapters, and 2 GE in wall z-wave switches. We got the zigbee sides of the Iris plugs to work quickly and without issue. The Zwave sides were all kinds of fits, but finally got them to connect. We also got 1 of the GEs to connect. Looking at the logs, the zwave sides never connected again after the inital connect. And the 1 GE that connected kept falling off.
Fast FWD 2 weeks, and we work on it again.
I bring a GE Zwave plug in module that I had been using at my home over the holidays. I had removed it from my hub. At this point my friend had moved the hub to the first floor, and placed it on top of a china cabinet that is as close to center of the house as we could get. So the hub is about 7 feet up in a room with 10 foot ceilings. Yes it is flat, on wood. At this point I cannot get the GE plug in module to connect. I can’t get the zwave side of the iris plugs to respond. a zwave repair says every device fails to update. We move the irus plugs into the same room as the hub, and still cannot get it to run a zwave repair without failing.
She runs to bestbuy and buys a new hub. (side bar, she got her V2 hub nov of 2015, it sat in a box for a year before she got around to proceeding with this project). New hub, in place, The GE plug in module connects right up. One of the Iris modules connects right up on the zwave side. At this point I am hopeful, that the old hub was bad and that was our issue. I move the GE module to the second floor, half way between the hub and the outside light that we want to control. BAM!! that GE switch paired up!! I think things are going well. But I cannot the the other GE switch to pair up. It did respond when I did the general exclusion to get it off the old hub. I move one of the iris plugs to the second floor, run e zwave repair, and all devices fail. The GE plug in module stops responding, the GE switch that did pair stops responding. I fuss with it more. I move the GE plug in to an outlet on the second floor that is ALMOST directly on top of the area the hub is in. We est it is about 5 feet from the hub on the first floor to the plug on the second floor, and we still have issue.
We ran out of time, so the project sits. The Zigbee devices have no issues so far, it is just zwave. She is going to see about getting more of the GE plugin modules, to see if we increase the density it will help. But I am at a loss. Any one have any ideas?
