Domoticz

Reads out a DHT22 temperature + humidity sensor and displays data on a webpage that is hosted by the ESP8266. Quite nice i must say!
But ofcourse i want the data in Domoticz, so i created this script:

Code: Select all

#!/bin/bash
# This script retrieves the temperature and humidity from the webpage
# generated by the code running on ESP8266 that is posted here
# http://harizanov.com/2014/11/esp8266-powered-web-server-led-control-dht22-temperaturehumidity-sensor-reading/

# Fill in variables
ESP_IP="192.168.4.248"
DOMO_IP="192.168.4.4"
DOMO_PORT="8084"
DOMO_IDX="121"

# Retrieve webpage and strip out relevant information and put information (position 13 & 16) into two variables (temp, hum)
curl -s http://$ESP_IP/dht22.tpl | grep "reading is" | awk '{print $13, $16;}' | sed 's/*C,//g' | while read temp hum
do
if awk "BEGIN {exit $hum <= 25 ? 0 : 1}"
then
	#echo "Dry"
    hum_status="2"
elif awk "BEGIN {exit $hum > 60 ? 0 : 1}"
then
    #echo "Wet"
    hum_status="3"
elif awk "BEGIN {exit (($hum >= 25)&&($hum <= 60)) ? 0 : 1}"
then
   	#echo "Comfortable"
    hum_status="1"    
else
    #echo "Normal"
    hum_status='0'  
fi	
# Send data to virtual sensor in Domoticz ("Temp + Humidity").
OUTPUT=`curl -s "http://$DOMO_IP:$DOMO_PORT/json.htm?type=command&param=udevice&idx=$DOMO_IDX&nvalue=0&svalue=$temp;$hum;$hum_status"`
done

I'm going to put this in my cron to run every minute.

Seems to work, but comments about improvements that can be made are always welcome. The humidity status (when is it 'comfortable', 'wet' etc) is based on a piece of Domoticz code: https://github.com/contactless/domoticz ... XNames.cpp

The temperature/humidity scraping part works fine, but i am not sure about the part that translates a humidity level to a state ('Comfortable', 'Wet').

unsigned char Get_Humidity_Level(const unsigned char hlevel)
{
	if (hlevel<25)
		return humstat_dry;
	if (hlevel>60)
		return humstat_wet;
	if ((hlevel>=25)&&(hlevel<=60))
		return humstat_comfort;
	return humstat_normal;
}

#define humstat_normal 0x0
#define humstat_comfort 0x1
#define humstat_dry 0x2
#define humstat_wet 0x3

bdw, is it not possible to send the update values from the ESP module directly to domoticz ?
I think i have read somewhere that you can use it in combination with 'MySensors' ?
Like making one gateway that receives updates from all node/childs ?
And able to send commands back from the gateway to the ESP (to control a light switch for example)

Oh and i found this: https://github.com/beckdac/ESP8266-transparent-bridge

This is really basic firmware for the ESP that creates a totally transparent TCP socket to ESP UART0 bridge. Characters come in on one interface and go out the other.

Do you already have a serial project to which you just want to add WiFi? This is your ticket. No more dealing with the AT command set.

I think when i connect the ESP8266 to my smartmeter' P1-port, i can install something like ser2net and have a wireless smart meter ?
Something to try soon

Anybody tried this already ? Got a few esp8266 incoming

Only i do not get it to work......

Some?

I have the board
I have the ide for arduino with loaded espaeasy.
I have sensors
I now how to compile and upload, to the board.
I do not how i set the boards in to the upload mode..

I mis the driver [ s]
I run windows 8.

And for my help a sample sketch for espeasy give me a smile...

You have to add a specific url, see this tutorial:
https://github.com/esp8266/Arduino/blob ... ds-manager

Looks great this ESP Easy project!

Piet,

What board od you have?
And what driver you did install?

And the line you mean is the for the install of the esp. [ that is n problem.]
And how do you get the board in upload mode?
