Thank you for the info.
OK, these toys are not a US version (that what I thought).
And who knows how they will integrate with HE.
You all are making me want a display panel above my ZEN32. Family would like it since they cannot remember all the buttons sometimes, and it would be a Wow factor when guests come over.

Forget about family. I myself cannot remember what is programmed for each button (specifically ones used rarely). My wife absolutely rejects all these double clicks and long presses (I have to program click and long press the same way). Highly customizable panel(s) with electronic labeling is a HUGE plus and very handy.
Would they have battery backup? LOL.
Most likely - no. But what for? What you are planning to control without power?
All configurations is stored in EEPROM and will retain during power outage.
I haven't thought it through, but it doesn't have to be an all-nothing-thing. I could have equipment powered up by battery or generator that I'd like to switch during a general outage.
You can use the current one in the US. The larger one is coming to the US and supports Home assistant out of the box.
By the spec voltage is 230V. I don't have any fixture with 230V available. All they are only 120V. So, either spec is incorrect or how it can be used on 120V circuits?
And where to buy this pannes in the US? I am not buying anything on Aliexpess,etc.
You can power them with 5v after removing the PSU.
This could be a good option for the Tabletop Controller application but definitely NO GO (NEC Compliance) for mounting in the existing electrical box.

Can you think of any outlets that have USB chargers in them?

My option is more on a DIY solutions side but I think it should be possible to use simple voltage doubler inside wiring box. (#0211) Simple Voltage Doubler Circuit in SMPS
Absolute most devices these days have switch mode power supplies. That means they don't really care if input is AC or DC. A voltage doubler of 120V will provide around 340V DC. (Peak-to-peak voltage for rectified 240V is 340V DC. So it should be close. Some more sophisticated schematic with triac might be more safe in a sense of lowering the output voltage to around 310V just in case)
Keep in mind electric shock risk factor when working with such high voltage things!

All these options are not NEC compliant and therefore NO GO.
I am EE with huge experience. Sure, I can come up with many different ideas how to power on these panels. But unfortunately neither DIY option will be in compliance with NEC which is a must.
BTW, I already installed few re-flashed NSPanels which are 100% NEC compliant, easy customizable and integrated with HE via HA <--> HADB. (Link for the project in the previous post above).

Confused by this - there are definitely USB outlets that are UL listed (and NEC compliant). For example this one from Leviton.
Is this the type of outlet that @JumpJump and you are referring to, or is it something different?
We are discussing a wall mounted option for these panels. Right?
In theory using an outlet with the USB Power Port is NEC compliant. But How to mount the panel to the outlet? I could be wrong but I assume mechanically it will not be an easy task.
There is hardware available to mount a tablet to a wall (with a recessed outlet behind the tablet). Something like that could be adapted for this use.
Maybe.
But I am all set with NSPanels (3 installed and 1 is still unboxed, cost was $59 when I bought them a while ago). This toy nicely fits into single gang box, NEC compliant, has 2 relays, 2 physical buttons and very nice highly customizable touch screen. First time it needs to be re-flashed which requires very minor soldering. After that all upgrades are wireless. It is native to HA and easy integrates with HE via HADB.

Bad idea. You should never connect home brew circuitry to the power mains. Always use a UL or similarly approved power supply to translate the mains voltage to the required DC level (volts and amps). The subtleties of safety compliance are very specialized. I'm an EE with 45 years experience and I wouldn't connect circuitry to the mains because while I don't know all the minutia of safety and protection I know enough to know it isn't for the hobbyist. Your insurance company would deny coverage from an electrical fire caused by a non UL approved device...
Just find a power supply for 120VAC that puts out the same DC as the 230 VAC power supply.

I was just trying to be friendly and helpful. Somonetimes people take something like that as criticism. Since this forum is international and a member posted about their screen solution I took the opportunity to share about Shelly displays. This because nspanel is often compared to the Shelly x1 display. Some good YouTube videos on that comparison.
Shelly display x2 is coming to EU this quarter and then the US shortly after. It supports landscape and portrait. It also supports HA out of the box. They will also be selling desktop boxes.
We have probably gotten off track a bit, but a tablet type screen is a premium look. Now, we need to show how these Shelly x2 screens support hubitat out of the box...
