When windows report that it cant open the com port then it normally means it can not communicate with the USB device.
Windows can normally open the com port without anything connected at all.
At least that is how it is for my devices, whether I use my Profilic, Cisco serial-to-USB or a bootstrapped NodeMCU.
Maybe there is devices behaving differently. I have just not seen them yet then.
Relax guys…no need to argue…
I am happy over any input…
How would i introduce the extra power to the setup?
Cant imagine that i can just jerry rig an old USB charger and plunge it on it?
Anything that provides very stable power. This is particularly important during the flashing phase when more power will be drawn. Some (most) cheap USB adapters will be problematic. Try what you have, but keep this in mind.
I have a separate, high quality 3.3V and 5V regulator that I can use on my breadboard when programming chips, but actually the power from my Mac’s USB ports are fine, so I rarely have issues. Just mind this: Most modern PCs and Macs have a high power USB port. Initially, these were dedicated ports. But now it can be any port, so best to make sure you have nothing else like an SSD plugged in that may compete for this power (and might’ve grabbed the assignment before your programmer).
You can use a powered USB hub
i just meassuered between GND and chip shield to see if i have a constant io0 ground and got 27k ohm…is that considered grounded io0 or good?
At this point i am actually grabbing every straw…
Next…i saw that people flash via eptool but they have bootlaoder bin and main bin …where can i obtain those files?
All i have is legacy or modern file format from esphome web download…
Does this loom like a successful flash?

Plugged flasher into usb and the leds went crazy and it booted…
Now i have this baby running again on my usb port, esphome shows me every data and i just updated esphome via ota…but when i unplug it all and bring it downstairs to the breaker box to its original power…all i get it that darn power light…
What does this RTS pin do…and why in the world does it occaisionally trigger this thing to boot
How? What exactly is the source? What voltage?
It’s usually for switching power supplies to degrade.
Did you try another PSU?
Is that a metal box?
Because if it is then it might be acting as a Faraday cage.
Original power is just 120 volts via 4 cables feeding the circuit board that chip lives on.
It has its own little step down and rectifier.
Degrade would be bad since device came fresh bought from manufacturer, ran 2 weeks with original software and then i tried flashing it, different psu would be heck of a rig job but will look into it
Since box is a metal cage, they come with a pittail wifi antenna that u mount through a breakout so that it is outside of mr farraday
By the way, much thx that u guys keep trying. I really appreciate that
If you have a multimeter, measure the voltage pin on the chip.
Good with the antenna, but you need a shielded antenna cable for the wire pull.
It is clos rot many power cables that all will cause noise.
Will try that
I am assuming the antenna is designed to for this application, especially since the other one that still aha the original firmware works like a charm
Nothing else expected! Some users sadly don’t get tired spreading FUD
It was not the antenna I referred to, but its placement.
We recommend that the radio USB sticks, like the skyconnect be moved away from the USB port chips due to electromagnetic noise from these.
It can be the same with an antenna and power cables.
Aren’t you realizing that you actively sabotaging @Darkyputz from getting help or is this just your intention?
