I have just had my house rewired and as such thought it would be a good time to bake in some smart tech into what is, essentially, a 100-year old pile of bricks. Rewire happens, all goes well and new kit is installed. I opted for Qubino DIN Dimmers (looks very nice and centrally controlled, no need for physical light switch) for control and the Aeotec Wallmote Quads as switches. I have some other devices which are mostly working OK but the real problem I have is with my lighting.
When I press a button on the Aeotec’s they flash, they vibrate and then nothing happens. If you are lucky after about 10 seconds you might get a light coming on. I have been doing some investigation as I am new to Smartthings and have completed a bit of troubleshooting…
- I have run the Z-Wave repair numerous times. It was reporting orphaned devices so I have cleared them off by force removing dummy devices with matching network ID. The test now completes without complaining at all.
- I have changed the device handlers for the Qubino’s from their custom DTH to a generic Z-Wave Metered Dimmer type. Exactly the same functionality but now we have local execution. THis has solved 99% of problem with the Qubino dimmers. They work prefectly from the app now and also Alexa seems a bit happier (would report non responsive device although would actually turn the light on or off)
- Have enacted QoS on my network. I have full Cisco Meraki network at home (FW, Switch, AP) and as such I can be quite granular with QoS. Anything from the Smartthings hub is prioritised above all else and forwarded ASAP (EF48 for the network geeks among you)
- Used enhanced monitoring on my WAN connection… This is the interesting bit and explains why step 2 sorted so much out. I have between 25-35% packet loss all day long and between 50-80ms latency which can spike to 2500ms if the line is under heavy load.
I think my problems stem from having about 25 orphan devices (now fixed) and also having an incredibly unreliable internet connection. I have solved the orphan devices and by moving the DIN Dimmers from cloud to local execution has fixed that. So it looks like the internet would be the thing to fix and everything else is a workaround.
Having just been quoted £12000 to get fibre installed to my property the workaround is starting to look pretty attractive… is there a local exec DTH that will work with the Aeotec Wallmote Quad? I don’t need the generic one to do everything, just register the button presses. I can change it back to the cloud based one if I need to change any device specific stuff and revert to the generic one after I assume?
To clarify, turning a Cubino dimmer on and off from the ST App takes less than a second and works brilliantly. Using the Aeotec Wallmote Quad to do it results in a long wait and that is if it does it all. Pretty sure internet is the problem so need something to process the button presses locally if possible. Failing that if anyone works for BT I could do with some Fibre in my house!
Would a group association help here? I don’t want to do direct association as it would remove the whole point of having a hub but surely there is a fudge to sort out the lag?
