HomeStatusDisplay - based on ESP Easy & MQTT & Node-Red

#1 Post by kalteLoetstelle » 23 Jul 2018, 02:02

Hello everybody,

First of all, please excuse my modest English.
This is also my first attempt at publication.
Please bear with me i try to give the best.

Inspired by Bernd Schubart's cool project (http://www.bernd-schubart.de/homestatus ... -im-blick/ ) i wanted to present something comparable on the basis of "ESP Easy".
Many, many thanks to him !

Image

However, I wanted to make the logic more flexible, so it was outsourced to "Node-Red".
(Node-Red also provides a great web dashboard, but this is not discussed here.)

My existing environment, running on a RaspberryPi:
Smart Home System : OpenHAB 2 (with MQTT Binding)
Data Hub : MQTT Broker Mosquitto
Logic Level : Node-Red

Sensors and actuators:
- Some ESP8266 running ESP-Easy with temperature and humidity or PIR sensors
- some Sonoff RF switches and S20 Smart sockets (running Tasmota-Firmware)
- some HomeMatic window and door contacts
- some Homematic radiator thermostats (RaspberryMatic <=> OpenHAB <=> MQTT:) )


Hardware required for the project:
- 1 x Wemos D1 mini running ESP-Easy.
(https://www.banggood.com/de/Wemos-D1-Mi ... rehouse=CN)

- WS2812 individually controllable LEDs in the appropriate format:
Since the representation is to take place in a small 10 x 15 cm photo frame I used a very compact design:
- 1 x 3 Piece 8Bit WS2812 individually controllable RGB LEDs
(https://www.banggood.com/3Pcs-CJMCU-8-B ... 8097201802)
These are a little thicker than LED strips due to the fixed PCB, but the 8 LEDs are only approx. 0.6 mm apart.

Alternatively for larger projects / frames, WS2812 LEDs can be separated individually from the Strips:
- 1 mtr LED-Stripe WS2812, individually addressable and separable
(https://www.banggood.com/1M-Non-Waterpr ... 8097201802
The stripe is a bit thinner, but the distance between the LEDs is longer.

Very little electronics are required for the standard wiring of the WS2812-LDs:
- 1 x 1000uF Electrolyte Capacitor
(https://www.banggood.com/de/10pcs-35V-1 ... rehouse=CN)
und
- 1 x Resistor with approx. 470 Ohm
(https://www.ebay.de/itm/10-Stck-127-Wer ... cIFO9dDfaQ Select 470 Ohm!)

- 1 x USB power supply, power approx. 1-2A, depending on number of LEDs
(https://www.banggood.com/BlitzWolf-BW-S ... rehouse=CN)

- a picture frame with sufficient depth
(Unfortunately I couldn't find one, so the electronics had to stay outside)

The wiring, also the assembly of the photo frame etc. is already shown very well in Bernd Schubart's project page:
http://www.bernd-schubart.de/homestatus ... -im-blick/

Today I would like to limit myself to the special features of the ESP-Easy and the logic in the Node-Red.

Here we go:

Settings in ESP-Easy:

First we need a connection to the MQTT-Server:
Image

Than we add the devices:

(The SHT30 device is an add-on. It is not required by this project, but also provides me with additional temperature and humidity from the location of the display.)

Configuration of the NeoPixel LED's
Image

Configuration of the MQTT - Import
Image

The Ruleset breathes life into it:

Code: Select all

// Init after Boot (to show some reaction):
// When the ESP boots, Set some LEDs to yellow to visualize the boot process
 On System#Boot do    
  NeoPixel,1,25,25,0
  NeoPixel,8,25,25,0
  NeoPixel,9,25,25,0
  NeoPixel,16,25,25,0
  NeoPixel,17,25,25,0
  NeoPixel,24,25,25,0
endon

// Normal operation, responds to MQTT output

on MQTTled#ledfarbe3 do
   NeoPixel,[MQTTled#lednr],[MQTTled#ledfarbe1],[MQTTled#ledfarbe2],[MQTTled#ledfarbe3]
endon

// Two reasons to extinguish all LEDs:

// 1.for visualization that the connection to the MQTT was established after Rebooting
On MQTT#Connected do
  Publish sensor/%sysname%/data/ip,%ip%
  timerSet,2,1
endon

// 2. If MQTT transmits led color "999" clear all LEDs
on MQTTled#ledfarbe3=999 do
   timerSet,2,1
endon

// Switch off all LEDs:
On Rules#Timer=2 do  
  NeoPixel,1,0,0,0 
  NeoPixel,2,0,0,0 
  NeoPixel,3,0,0,0 
  NeoPixel,4,0,0,0 
  NeoPixel,5,0,0,0 
  NeoPixel,6,0,0,0 
  NeoPixel,7,0,0,0 
  NeoPixel,8,0,0,0 
  NeoPixel,9,0,0,0 
  NeoPixel,10,0,0,0 
  NeoPixel,11,0,0,0 
  NeoPixel,12,0,0,0 
  NeoPixel,13,0,0,0 
  NeoPixel,14,0,0,0 
  NeoPixel,15,0,0,0 
  NeoPixel,16,0,0,0 
  NeoPixel,17,0,0,0 
  NeoPixel,18,0,0,0 
  NeoPixel,19,0,0,0 
  NeoPixel,20,0,0,0 
  NeoPixel,21,0,0,0 
  NeoPixel,22,0,0,0 
  NeoPixel,23,0,0,0 
  NeoPixel,24,0,0,0 
endon
This completes the configuration of the ESP Easy.
ESP will subscribe to the MQTT and when the "MQTTled#ledfarbe3" changes, the values of the corresponding LED will be applied.

Node-Red Configuration

Importing the following string in Node-Red (via

Copy the following string to the clipboard and switch to Node-Red web interface.
Select "Import => From Clipboard".
The "Status display" flow should now be available.

Code: Select all

After the import, Node-red should show the new flow "Statusanzeige".

Using the examples, the configuration must now be adapted to your own values, names, sensors, actuators, etc.

Have Fun !

I hope to give something back to the community with this.
Comments and questions are expressly welcome, I will try to answer as soon as possible.

Hello,

thank you for this great tutorial.

I'm a beginner

I started and tried to do the same in openhab. It's ok for espeasy and the rules but I can not send commands from openhab. Can you add an example of a "openhab items" so that I understand the configuration?

example: Switch Neopixel1 {mqtt = "> [broker: xxxxxx


thanks again

Hi,

So far "openhab" is not involved,
except that openhab items are queried from Node-Red and their status is written to the MQTT.

In the following way:

The status is then read from the MQTT and analyzed as described above to switch the LEDs.

i think its posible to do something like this:

Code: Select all

/* display_test.items */
Switch Status_01 	  "Status_01"  (LR,gLight)    { mqtt=">[mosquitto:stat/na/na/status/01/status:command:*:default], <[mosquitto:stat/na/na/status/01/status:state:default]" }
Switch Status_02 	  "Status_02"  (LR,gLight)    { mqtt=">[mosquitto:stat/na/na/status/02/status:command:*:default], <[mosquitto:stat/na/na/status/02/status:state:default]" }
Switch Status_03 	  "Status_03"  (LR,gLight)    { mqtt=">[mosquitto:stat/na/na/status/03/status:command:*:default], <[mosquitto:stat/na/na/status/03/status:state:default]" }
Switch Status_04 	  "Status_04"  (LR,gLight)    { mqtt=">[mosquitto:stat/na/na/status/04/status:command:*:default], <[mosquitto:stat/na/na/status/04/status:state:default]" }

Code: Select all

sitemap display_test label="Display Test" {
    
    Frame label="Stati" {
        Switch item=Status_01
        Switch item=Status_02
        Switch item=Status_03
        Switch item=Status_04
    }
}
You get an basic-UI Sitemap like this:

But .. Why don't use the Noed-Red Dashboard ?

The original Node-Red Flow can easily be extended by a few Dashboard Nodes and displayed as a Node-Red Dashboard.

Thanks for this post. There are some really good ideas in here.

I found these little NeoPixel strips that might make a good display indicator. You might want to use every second LED though.
