It is on the same circuit and throwing interference.
I have an audible thump out of my sub every time we flip the wall switch to the ceiling fan.
Is this possible?
Yes.
Will you have the same level of functionality and convenience? No.
Will it be easy? No.
There are tricks you can play with your firewall and other networking pieces to prevent devices from calling home. But those devices have to have local API’s exposed so you can still control them.
Consumer HA companies rolled out WiFi cloud solutions because it was easy. Consumer could get started after buying just one device. Not need for a HUB and compatibility. Then they learned that cloud data can actually be pretty useful.
Hopefully Matter will cut into this mess. Part of the standard is that all devices should have local control and cloud access should be only for added functionality.
I’m slowly replacing my Control4 system with DIY.
The hardest part for me has been finding a good controller that is powerful but doesn’t require you to make HA a second full-time job (looking at you Home Assistant).
I’m hoping Samsung will come out with a good Matter controller soon.
As long as you are not doing AV distribution, you can pretty easily replace everything C4 does with DIY hardware.
You want reliable? Forget WiFi.
Power is measured in amps or watts.
Maybe it is rated for a total of 15 Amps @ 5vdc total across all ports (which would be a really nice hub!). IF it shows the total power being consumed in real-time, that would be an awesome feature for some people.
The USB-A port is rated for 5vdc maximum and all USB-A devices are 5 volts. SO having a 15V hub would not make any sense.
USB-C can do higher.
Because the learning curve is too steep for somebody who doesn’t see HA as their full-time hobby. They only want a completed project.
I’m software developer fluent in Linux. I have given up on Home Assistant. I’m back to SmartThings and Alexa waiting for a proper Matter controller to hit the market.
You can’t because that HUB has individual manual switches for each output.
The only way to use that HUB for any sort of automation would be to buy SwitchBots for each output and have them flip the switches for you.
Depends entirely on the valves.
If they are WiFi valves with a cloud API exposed to Google Home. No hub required, google controls them through the cloud. Which also means they won’t work if the internet is down.
If they are ZigBee/Z-wave/Thread valves. You need a hub that speaks that protocol. The biggest benefit is everything works locally and will still work if the internet is down.
The Meross doesn’t connect to your existing garage door opener at all. There are no wire between the two units.
The Meross just pretends to be the remote control. It receives commands via WiFi then pretends like it is the remote control pressing the button.
So it will only work with your opener if it know the wireless standard used by it. Check out their compatibility list.
If you opener has a remote release contact on the PCB, you could do the same as the Meross with a smart relay and a door sensor.
