This isn't about your switches, per se. But I bought your switches to convert my regular switches to wifi. Everything went fine, all the switches have worked flawlessly. But I had a related problem with another device.

The reason I bought your switches is because they support Cortana. I'm at my home office desk all day and I wanted to be able to control everything without having to find my phone. I just wanted to tell Cortana to do whatever right from my desktop computer. It worked perfectly. But then I decided that this was too good to just use in the office. So I bought a Harman Kardon Invoke speaker with Cortana. It's beautiful and the sound far exceeds any Alexa or Google device.

But then the problem. After a few commands and waiting about 10 minutes, Cortana would respond to any command with 'try again later' or 'I can't connect to the Internet right now'. It worked on my PC but not on the speaker. A reboot of the speaker made everything alright. Sound familiar?

After some research I found out that setting up a Quality of Service rule in the router might help. Sure enough, when I did that for the speaker it hasn't disconnected since. From what I've read this probably was caused by my adding so many devices to the home network. The number of devices that are using the network had doubled.  Reserving a priority for the speaker allowed it to remain online.

Of course, I don't know if this would be a solution for others who are having problems with your switches, but I thought you might like to pass it on to your developers and see if there is something that can be done in the firmware to alleviate the problem.

Thanks for having Cortana integrated into your switches. I can now turn on lights with your standard HS220 switch. Turn on a dimmer with your HS200 switch. I plan on adding another dimmer to the fan in the bedroom along with your fan control switch.

FYI, I'm working on a new video for my YouTube channel (Old Guy Geek on Windows) about all of this and I will be using your switches exclusively.

Hope this helps someone.

Those devices were not listed as being part of this issue so there is not any beta firmware currently available, that we know of.  Can you provide details of the products you have and any particulars to the issues they are having.

Details for the products are model and hardware version as well as current firmware version.  

thanks

Please check just to confrim that the devices are on the most recent firmware.  Even if they were installed just a month ago they may not have updated or there may be a new update available. 

Next i would look at your network settings and just make sure the devices are getting the best signal possible.  Lastly take a look at your router logs before doing a restart.  This way we can see what the router is indicating as an issue and work to a resolution.
