I’m not sure if this is the right Forum but my Harmony Hub will lock up randomly during the day. I get a red light on it and I don’t know what’s causing it. It’s unable to be used from the app with the remote so it just is locked in place.
I have a WeMo switch attached to it so that I can remotely reboot it but this doesn’t seem like normal behavior and I’m not sure why this would happen.
I have this running with my SmartThings and Alexa devices
The Harmony hub solid Red light happens when the harmony hub is not available, most commonly because it is either syncing with the cloud account or downloading a firmware update or your Wi-Fi is offline.
If the app is also unresponsive, that sounds like an issue with the harmony cloud.
Also, if I remember correctly, have can only operate on 2.4 GHz, so if your other devices on 5.0 You might not notice issues with those. Make sure your phone or tablet is on the same network as your hub.
Then Try going to the website on a laptop and synch the hub from there.
I also have experienced the ‘red light’ Harmony Hub Lockup which is frustrating. The Hub takes about 45 seconds for it to recover to a green normal condition and responsive to the remote. My NetGear NightHawk router shows DHCP request each time, which would account for the hub’s soft reboot.
I removed the Ecobee integration and left only SmartThings in the Harmony Home Automation device list. It locks up less frequently now. I would remove SmartThings, but I think I need that for the Alexa voice command integration I desire.
I really doubt it’s nothing on my wireless router AP side, since all other wireless devices nearby (RoKu, Blu-Ray, TiVo, Camera, etc) all acquire a string signal and do not loose the signal from their logs.
I think that a recent Harmony firmware release has been problematic and Harmony support is chirp-chirp?
I was also havijng issues with my harmony hub yesterday, freezing up and reassigning all the buttons on harmkny remote without any warning. Seems to be working better now.
I can’t remember I’m afraid, I know I’ve had to plug it into a computer to do various things occasionally, can’t remember if one of them is a firmware update.
I’ve had my Harmony Hub less than a month and it’s been wonderful, until now it’s suddenly randomly showing just red LED and not responding to remote till about a minute after pressing a button. Today I plugged it into the MyHarmony software on my MacBook and sync’d it. If it persists I’m going to try the various stabs in the dark I’ve read about:
Force the WAP to a specific channel, not auto-select
Mine are both older but they do not stand by the product. I have have tickets open for a year without resolution. I have the hub now attached to a smart switch and cycle it daily which helps a little bit.
