Hello,
I’d like to introduce
This is Alpha release, support Native API Component — ESPHome
there is no support for bt proxy and encryption, if possible, test the node
Interesting. What configuration do you need on the ESPhome side?
I use MQTT throughout since that is easy with ESPhome. Sensor data goes to a standardised topic structure. Inputs generally use existing topics because I've not actually implemented any external controls as yet. If I did, I would choose a standardised topic structure aligned to the output structure.
the ESPhome protocol supports the announcement of the services that are in the equipment, you see, for example, all the operating modes of the air conditioner ( supportedFanModesList, supportedCustomPresetsList) as far as I know, mqtt and mqtt discovery (HA MQTT discovery ) does not announce this
well, the main idea is to communicate directly with esphome
Ah, the native api thing, I see. I've skipped over that before because I don't use Home Assistant.
Not sure all of their listed advantages over MQTT stack up.
Efficiency isn't an issue unless you need ms level responses or are sending crazy amounts of messages (in the hundreds of thousands at least).
"One less single point of failure" - you could equally argue that you now have N points of failure where N is the number of ESP devices 
. You now have to monitor multiple devices for failure. With MQTT, while the broker going down stops all comms, a device going down is automatically registered on MQTT through the use of the Last Will and Testament feature. With a sensibly chosen topic structure, a single, simple flow in Node-RED can monitor and alert on all devices.
"Stability" - never had any problems with ESP device stability since I moved to ESPhome! Nor with MQTT stability.
I think MQTT discovery is an HA thing only? MQTT doesn't have native discovery and this could indeed be useful when handling dozens to thousands of devices. Thankfully, not something I need to do - I have around 5 or 6 
Sorry, not trying to undermine what you are doing, it is a great addition. Just trying to get my head around the different ways of working.

Off topic from this post, but @TotallyInformation I am intrigued about your (home?) automation solution. If you don't use HA, what do you have for controling/measuring or centralization of you devices? Do you have a post about it?
Just to know
Thanks
Jav
@TotallyInformation here is a use case.
I am a farmer that used Node-RED and ESPHome to finesse our boreholes to find the sweet spot where you can pump from a borehole without it running dry during a brutal five year drought. Using flow sensors (and again, mostly Node-RED), it also detects air in the pipe and shuts down a pump to save it from burning out (they don't like sucking air).
Using this tech, I found 40,000 litres of water a day that I didn't have before. For context, I need about 5 times that. So when it's the choice between dust and 40,000 litres, I'll take the water, thanks.
I also helped a bunch of other farmers do the same thing. It was massively impactful.
Home Assistant only needs to be there to deliver ESPHome to Node-RED.
Then for reasons I won't get into here, HA becomes a threat actor (ie not safe to run on home network). I would say it isn't to most users, but to people with my background, it represents a threat, because we don't live where you do, and the landscape is real different out here. I shouldn't have to tell you why my consent statement is No; it just is.
So then I realised that, OK, it's actually only ESPHome that's useful, and since most of the people I've helped share the same specific experience that makes HA a threat actor, I have to look at ways of removing HA from the equation.
This here node-RED-contrib-esphome thingy will be life changing.
Thank you, thank you, thank you @twocolors for your work on this. You have no idea how many lives this will affect.

I just did a quick ESPHome test on an ESP8266 NodeMcu, with an i2c HDC1080 (temperature and humidity sensor) connected.
I can clearly see my sensors in the Web_Server:
Now, I would like to display my sensors in NR with node-red-contrib-esphome but I cannot connect to it:
there is nothing in the drop-down list
My question @twocolors : is Home Assistant required for node-red-contrib-esphome to work in NR ? Because I don't use it like @TotallyInformation .
Otherwise, what should I add to my .yaml Configuration for the link to work ?
(otherwise I will switch to MQTT...)
Can't really help as I don't use HA. But I can say that ESPHome can simply output to MQTT and that's how I use it.
I don't want to use HA either. So I found this node-red-contrib-esphome interesting to directly link ESPHome and NR without any other addition.
Because in the documentation it is not clearly said: "with or without HA", I was hoping that my .yaml was missing some lines to work.
I wanted to do an easy "plug and play" test... but if i have to install HA for it to work, I'll let it pass (even if the MQTT option was interesting 
).
There is no need to use the esphome contrib node or HA, just use MQTT directly.

As both I and Colin have said, you can simply output and input to/from MQTT direct from ESPHome. That is how I use it.
I split my ESPHome config into separate YAML files because much of my config uses the same settings and sensors. Here is the MQTT YAML I use in all my ESP's.
# Configuration for the MQTT Broker.
# NB: This configuration does not use Home Assistant (HA). It uses TotallyInformation's standard MQTT Schema for ESP devices.
#
# The configuration variables must be set in the master YAML file.
mqtt: # Home MQTT Broker
broker: $mqtt_broker
username: $mqtt_username
password: $mqtt_password
topic_prefix: $mqtt_prefix

thank you, I'm saving for my next test 
I think that really should be in the readme (and pretty much the first, largest, boldest item in there)
Is it mention in the built-in help?

ok, so I add the line api:in my .yaml config :

api:
should I also install: $ pip3 install aioesphomeapi ?
because I still can't connect to my ESP32 ESPHome :
First trial worked fine for me
- adding api: to -yaml and re-flashed the ESP device (Wemos C3 mini)
- installed node-red-contrib-esphome
Device was found at first trial. (Both my RPi 4 running Node-RED and the Wemos devices are on the same network)
Hi Walter,
that's what I did but I don't understand why my device is "Disabled" :
the log of my espHome tells me "No client connected to API. Rebooting...":

A connection is interrupted somewhere !? Does yours say “Disabled” too? Or something else ?
Hello SuperNinja, nice to see you again!
In my setup it looks ok. It worked right away when I tried it, only thing I did first was adding the api: to the .yaml and reflashed the device. Could it be something else in the .yaml configuration that is missing or so? I can show mine, just need to strip out some passwords etc from public audience
