Hi,
I stumbled across ESPHome and it seems to be a nice and easy way to integrate ESPs with different sensor through MQTT. There is support for the usual sensors and everything is configured nicely using yml and even allows OTA-Updates. Has anyone already tried it?

Good Find! I have been using ESPEasy for a while but always good to see free solutions.
I use this framework on ESP32 with multiply (3 currently) MiFlora sensors to report their data via MQTT to OpenHAB. Works beautifully! And all this with just few lines of code:
esphome:
name: bt
platform: ESP32
board: nodemcu-32s
wifi:
ssid: "***"
password: "****"
ota:
mqtt:
broker: "192.168.*.*"
esp32_ble_tracker:
sensor:
#node uptime [s]
- platform: uptime
name: "Uptime"
#RSSI of MiFlora BT signal
- platform: ble_rssi
mac_address: "C4:7C:8D:**:**:**"
name: "M1 RSSI"
- platform: xiaomi_miflora
#MiFlora readings
mac_address: "C4:7C:8D:**:**:**"
temperature:
name: "M1 Temp"
moisture:
name: "M1 Moisture"
illuminance:
name: "M1 Illuminance"
conductivity:
name: "M1 Soil Conductivity"
With above setup I have MQTT topics:
bt/sensor/uptime/state
bt/sensor/m1_rssi/state
bt/sensor/m1_temp/state
bt/sensor/m1_moisture/state
bt/sensor/m1_illuminance/state
bt/sensor/m1_soil_conductivity/state
Documentation is also very clear, with examples, which helps a lot at the beginning.
I highly recommend!

I found it a week or two ago.
I have a Sonoff 4ch pro I loaded with it. Works great, responsive. Has built in auto restart on WiFi drop out. The status led is a nice touch.
I have attached mine below, i use it for raising and lowering my projector screen.

ESPHome is great tool, what’s nice feature is indeed integration with HA and ability from HA do OTA of your devices…
integration with OH2 would be terrific!
i am Kind of a noob i guess…
i tried and was not able to understand how to flash them? how to create a bin file?
as we dont use HA i just droped it… a litle guide will be great!
I have followed guide: https://esphome.io/guides/getting_started_command_line.html
You will need working python environment in your system, if not installed yet you can follow steps described here https://docs.platformio.org/en/latest/faq.html#faq-install-python
Good luck!
Hi thanks i will give this a try !
Hello, I have an ESP32 flashed with EspHome that sends MQTT data that I can see in openHAB.
Unfortunately I am not able to persist this data in InfluxDB and Grafana although I followed all the steps.
I really don’t know how to debug this.
Can you help?
I can provide all relevant config files once I get home.
Hi @bbogdanmircea, first of all, welcome to the openHAB community!
Your issue is not esphome related.
Do you have any other openHAB items persisted in influxdb and confirmed working? If not, I suggest start first with https://www.openhab.org/addons/persistence/influxdb/#influxdb-0-9-and-newer-persistence , get persistence working, and only then start playing with Grafana. Step by step 
@kewld, I’m using just one ESP32 for all my miflora sensors (of course sensors needs to be in close proximity to ESP32, in my case it is ~7m max, open air (not counting tree and flowers in between ).
Please be aware, that with release 1.14 miflora component was renamed from - platform: xiaomi_miflora to - platform: xiaomi_hhccjcy01 - just follow documentation Xiaomi HHCCJCY01 BLE Sensor.
Hi folks,
maybe I’m blind, but how does one send a state to an esphome mqtt topic?
I’m using this on a wemos D1 (ESP8266) to control a connected argb led-strip…
this is what I can sniff from my mqtt broker
topic: argb_controller_01/light/fastled_ws2812b_light/state
{"effect":"None","state":"OFF","brightness":168,"color":{"r":255,"g":255,"b":255}}
so I added this to my mqtt.things
// argb_controller_01
Thing topic ARGB-Controller-01 "MQTT - ARGB-Control-01" @ "None" {
Channels:
Type string : effect "Lichteffect" [
stateTopic="argb_controller_01/light/fastled_ws2812b_light/state",
transformationPattern="JSONPATH:$.effect"
]
Type switch : state "ONOFF State" [
stateTopic="argb_controller_01/light/fastled_ws2812b_light/state",
transformationPattern="JSONPATH:$.state"
]
Type string : brightness "Brightness" [
stateTopic="argb_controller_01/light/fastled_ws2812b_light/state",
transformationPattern="JSONPATH:$.brightness"
]
Type string : colors-r "Red" [
stateTopic="argb_controller_01/light/fastled_ws2812b_light/state",
transformationPattern="JSONPATH:$.color.r"
]
Type string : colors-g "Green" [
stateTopic="argb_controller_01/light/fastled_ws2812b_light/state",
transformationPattern="JSONPATH:$.color.g"
]
Type string : colors-b "Blue" [
stateTopic="argb_controller_01/light/fastled_ws2812b_light/state",
transformationPattern="JSONPATH:$.color.b"
]
}
and these items
// ARGB-Controller-01
String ARGBControlEffect "Light-Effect" <none> (gARGB01) { channel="mqtt:topic:MosquittoMqttBroker:ARGB-Controller-01:effect" }
Switch ARGBControlState "Switch" <none> (gARGB01) { channel="mqtt:topic:MosquittoMqttBroker:ARGB-Controller-01:state" }
String ARGBControlBrightness "Brightness" <none> (gARGB01) { channel="mqtt:topic:MosquittoMqttBroker:ARGB-Controller-01:brightness" }
String ARGBControlColorR "Color R" <none> (gARGB01) { channel="mqtt:topic:MosquittoMqttBroker:ARGB-Controller-01:colors-r" }
String ARGBControlColorG "Color G" <none> (gARGB01) { channel="mqtt:topic:MosquittoMqttBroker:ARGB-Controller-01:colors-g" }
String ARGBControlColorB "Color B" <none> (gARGB01) { channel="mqtt:topic:MosquittoMqttBroker:ARGB-Controller-01:colors-b" }
so far so good, I can display all item states but how do I change a state? I can’t find a command topic,
how can I do this??
thanks
Dan
Hi Dan, you need to extend your mqtt.things file with commandTopic section to be able to send commands to esphome device. Topic to send commands, in your case, is argb_controller_01/light/fastled_ws2812b_light/command. Good luck!

Thanks I will try that…
only thing that gives me headache is the fact that all key/value pairs are in the state topic…
my tasmota driven sonoffs have different topics for each key/value pair…
regards
Dan
