I tried to run ecowater.py at the Putty terminal. I have hassio in ubuntu docker.
I think it fired correctly.
Enter the command
"user @ server: ~ $ python3 /usr/share/hassio/homeassistant/python_scripts/ecowater.py
Hi majdzik,
Thank you for your feedback.
I am running Hass.io, if I try to run a python command in the ssh terminal it says “command not found”. There is no “/usr/bin/python3” installed. I don’t know how Hass.io is supposed to run python scripts 
Hi,
Maybe you don’t do this while logged in to the hassio terminal.
What machine do you have hassio placed on? Rapberry? Try to run the script from the main machine system (root). I made CRON to run the script every 1 min.
I used the “Terminal & SSH” add-on from the hass.io supervisor store.
I am running hass.io as a virtual machine on a VMware ESXi Supervisor. I understand the principle of running the script via python command line and add it as a cron, but to be honest I am a bit confused about how hass.io is working with it s own virtual layers and what to connect with SSH then
I’ve been trying to see if it’s possible to just use the webpage card to access wifi.ecowater.com where they have graphs for salt levels, water usage, current water flow, average daily water usage, and projected number of days left. Unfortunately I just get an error message saying the site was “blocked by response.”
So after going further and further with my HA installation, I managed to convert the python script from Kyle Johnson to an AppDaemon app 
Here is the code of the ecowater.py file (to be placed in the ‘appdaemon\apps’ folder) :
import mqttapi as mqtt
import datetime
from datetime import timedelta
import requests
import json
import re
#
# Retrieve data from EcoWater interface and publish to MQTT
#
# Args: ecowater_minutes, ecowater_dsn, ecowater_email, ecowater_password
#
# Credits : Thanks to Kyle Johnson for the original code (https://www.gnulnx.net/2020/02/18/ecowater-api-scraping/)
#
# Converted to AppDaemon by kalhimeo
#
class EcoWater(mqtt.Mqtt):
def initialize(self):
# Run every X minutes
self.run_every(self.run_parsing, datetime.datetime.now() + timedelta(seconds=3), self.args["ecowater_minutes"] * 60)
def run_parsing(self, kwargs):
# Regex to match the hidden input on the initial log in page
request_validation_re = re.compile(r'<input name="__RequestVerificationToken" type="hidden" value="(.*?)" />')
# The serial number of your ecowater device
dsn = { "dsn": self.args["ecowater_dsn"], }
# The initial form data
payload = {
"Email" : self.args["ecowater_email"],
"Password" : self.args["ecowater_password"],
"Remember" : 'false'
}
# The headers needed for the JSON request
headers = {
'Accept': '*/*',
'Accept-Encoding': 'gzip, deflate, br',
'Accept-Language' : 'en-US,en;q=0.5',
'X-Requested-With': 'XMLHttpRequest',
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',
'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:73.0) Gecko/20100101 Firefox/73.0'
}
with requests.Session() as s:
# Initial GET request
g = s.get('https://www.wifi.ecowater.com/Site/Login')
# Grab the token from the hidden input
tokens = request_validation_re.findall(g.text)
# Add the token to the form data payload
payload['__RequestVerificationToken'] = tokens[0]
# Log in to the site
login = s.post('https://www.wifi.ecowater.com/Site/Login', data=payload)
# Add the correct Referer header
headers['Referer'] = login.url + '/' + dsn['dsn']
# Query the JSON endpoint for the data that we actually want
data = s.post('https://www.wifi.ecowater.com/Dashboard/UpdateFrequentData', data=dsn, headers=headers)
# Load the data in to json
jsonv = json.loads(data.text)
# Delete the elements that we don't want
del jsonv['water_units']
del jsonv['time']
# Publish each piece of json data in to mqtt
for d in jsonv:
self.mqtt_publish('ecowater/' + d, jsonv[d])
You need to add the app in the apps.yaml and provide some parameters :
EcoWater:
module: ecowater
class: EcoWater
ecowater_minutes: 60
ecowater_dsn: 'your_ecowater_serial_number'
ecowater_email: 'your_email_account_for_ecowater_portal'
ecowater_password: 'your_password_for_ecowater_portal'
You can then use the MQTT data as sensors and binary sensors in HA, example :
binary_sensor:
- platform: mqtt
name: Ecowater Online
state_topic: "ecowater/online"
payload_on: True
payload_off: False
sensor:
- platform: mqtt
name: Ecowater Salt Level
state_topic: "ecowater/salt_level"
Available binary sensors : online, recharge, out_of_salt
Available sensors : salt_level, salt_level_percent, water_today, water_avg, water_avail, water_flow, out_of_salt_days
That’s it , have fun !
Hi, I have the following error in AppDaemon.
WARNING AppDaemon: Unknown domain (default/mqtt) in call_service from EcoWater
How can I solve this?
Did you install MQTT broker (add-on / integration) in HA ? Did you activate and configure MQTT in AppDaemon config ?
Hi,
the broker is installed.
But what do you mean by activate and configure MQTT in AppDaemon?
I’m a Newbie to MQTT.
check your appdaemon.yaml config file in your appdaemon folder.
You should have a MQTT section in your plugins which looks like :
MQTT:
type: mqtt
namespace: mqtt
verbose: True
client_host: mqtt_ip
client_port: mqtt_port
client_id: homeassistant
client_user: username
client_password: password
More details : https://appdaemon.readthedocs.io/en/latest/CONFIGURE.html#configuration-of-the-mqtt-plugin
Thanks, working now.
Great help.
Is there something like a beginnerguide for MQTT?
glad that it s working for you too !
I am sure there must be beginner guides, but I don t know any
The app is running good, I get the right values, but there is one warning.
Is there something I have to do about it?
WARNING AppDaemon: callback run_parsing() in EcoWater has now completed
Yes i have the same, i don t know if this is due to a debug level, or if I should have some default log line at the end of the script to confirm it s execution. I am still new with appdaemon scripting as well
@kalhimeo excellent work with the script and instructions above, worked like a charm for me in first attempt.
Thanks a lot 
@kalhimeo is there way to avoid putting plain text values for DSN, username and password in app.yaml? I tried moving these values to secrets.yaml but the integration stopped working and I could not figure out a way to make app.yaml read the DSN, username and password from secrets.yaml file.
I have no idea, I am still quite new with these things 
sorry
@kalhimeo
Great thanks for this scripts and instructions indeed!
I got it working almost directly with your instructions.
Thanks a lot… 
@kalhimeo you did it perfectly, I was not starting the AppDaemon correctly. I’m able to put DSN, email and password in secrets.yaml and it is working like a charm!!
Thanks!
The integration was working for couple days like a charm, but yesterday, without any changes it disconencted and now I cannot get any data from ecowater. I can login to the ecowater website and mobile app without any issues, but the data are not coming to HA. Has anybody seen similar issue?
