Esphomelib - library to greatly simplify Home Assistant integration with ESP32

kap · June 6, 2018, 11:30am

Looks very good so far. I saw your note in the docs “In the future, this integration will be expanded to support reading RSSI values and hopefully support lots more devices like tracking smartphones and reading temperature values from BLE sensors.”

I’d love to put an ESP32 outside to drive a drip irrigation valve and be able to read (Bluetooth) miflora values and publish it on MQTT for HA to use.

Any idea when reading BLE sensors will come in?

Yeah sure it’s on my list, but that list is quite long… The problem is that I don’t own any BLE sensors (which send temperature values) and they seem quite expensive. Do you know of any cheap BLE-enabled sensors (~10$)? I’m thinking of maybe buying one as BLE is an interesting standard

The Miflora is a good device to use as an example. It’s fairly cheap also ~10-15USD.

Close enough to 10 (if measured in euros )

As @Landrash said, Miflora is very popular among the Home Assistant crowd, and runs about 13 USD.

Thank you! Just ordered one from eBay (I’m not a big fan of AliExpress) and will try to add support for it when it arrives - Gotta say that one @Petrica posted really looks quite dope (from a design perspective). So I’m already excited to have it arrive

@OttoWinter is there any chance of including control for digital LED’s? I found this earlier today as linked from another thread on this forum and thought it would be a nice addition to your awesome work to have digital LED control since the NodeMCU’s make such a neat little controller for this type of thing

You mean individually addressabld lights like WS2811 or neopixel rings? See the FastLED lights https://esphomelib.com/esphomeyaml/index.html#light-components

sparkydave · June 7, 2018, 5:35am

yep, thats what I was thinking of… you already have it sorted, although to have more effects would be sweet, any chance of including these? (I’m just now reading up on how to do this from your page but it seems way above my skill level)

Man, This Thing is Great.
You have no Idea how much easier it has made implementing home automation.!! Actually, I’m guessing you do
I have a small Issue tho. The OTA update wont work using the Hass.io web interface. It tries to upload to sensorname.local . I have an internal DNS namespace called internal.local (imaginative I know).
The HASS Server quite happily resolves sensorname.internal.local but it cant resolve sensorname.local.
I tried to Cheat and named my sensor something.internal, so then it tried to connect to something.internal.local but you cant have a fullstop in the sensor name.

Any idea’s on where I can make the software append the correct DNS suffix?

Thanks

See the domain parameter of the wifi: section courtesy of @HeMan https://esphomelib.com/esphomeyaml/components/wifi.html

wifi:
  # ...
  domain: .internal.local

knottyau75 · June 9, 2018, 10:34am

Thanks,
Works perfectly

Rodolfo_Vieira · June 9, 2018, 5:30pm

@OttoWinter my code is:

esphomeyaml:
  name: aaaa
  platform: ESP8266
  board: nodemcuv2

wifi:
  ssid: 'Casa'
  password: 'SECRET'

mqtt:
  broker: '192.168.1.85'
  username: 'username'
  password: 'password'

# Enable logging
logger:

ota:
  password: 'SECRET'

And when i click upload… i have this error;

How i can solve?

knottyau75 · June 9, 2018, 11:02pm

Hi Rodolfo,
Loos like you had the same error I had. you need to setup your domain Information. See the above post by myself and Otto.

Rodolfo_Vieira · June 9, 2018, 11:39pm

@knottyau75 hi friend… so its like a:~

wifi:
  ssid: 'bla bla'
  password: 'bla bla bla'
  domain: .internal.local

???

nickrout · June 9, 2018, 11:50pm

Yes that is correct.

Rodolfo_Vieira · June 9, 2018, 11:53pm

nop, doesn´t work for me…

nickrout · June 9, 2018, 11:58pm

What is the hostname of your device?

Fing (android app) is a good way of discovering this)

Rodolfo_Vieira · June 10, 2018, 12:07am

ok i read this:

To do this, first plug in the USB cable of the ESP into a USB port of the device esphomeyaml is running on and wait until you see a “Discovered new serial port” message (in some cases you need to restart the add-on). Select the upload port in the top navigation bar and press the big “UPLOAD” button

so, i disconnect my nodemcu of my PC, and connect it again on USB of my RPI… and…

now works

This is a great easy to understand project… I’ve got the basics working… however I am running into a problem that should be easy to solve but I can’t seem to get this working…

I am trying to control an active low relay. With the default GPIO switch config I have everything working… however on is off and off is on… and a reboot of the ESP8266 NodeMCU V2 defaults the relay to an on state…
This is my config…

switch:
  - platform: gpio
    name: "Pool Light"
    pin: D1

I have also tried to use the inverted option

switch:
  - platform: gpio
    name: "Pool Light"
    pin: D1
    inverted: True

With that config… homeassistant seems to keep the switch always on (i.e. if I toggle to off in UI, it just toggles back on")

I think I need to use the following config to set the mode of the D1 pin on startup, but I can’t figure out where to do this in the YAML to have it default the pin to high (i.e. relay off) on startup?
mode: INPUT_PULLUP

Any help in getting this working properly with active low relays would be very appreciated!

Thanks!
