Displaying Seneye in Reef-Pi

[TCoach]

Hey everyone,

While I wait for some more funds to be freed up for additional hardware, I have been able to pull in Seneye data into my reef-pi. Due to limitations of the Seneye api, data is only available 2x an hour.

Thought some of you might also like this.

API code:
/home/pi/seneye/seneye.py

import requests
import os
from pprint import pprint


__BASE_URL__ = "https://api.seneye.com/v1/devices"

username = "user"
password = "pass"
rootDir = "/home/pi"
workDir = "/ReefData/seneye"

seneye_data = {
"nh3": 0.0,
"nh4": 0.0,
"o2": 0.0,
"ph": 0.0,
"temp": 0.0
}

use_fahrenheit = True

def get_devices():
auth = {"user": username, "pwd": password}
device_resp = requests.get(__BASE_URL__, auth)

if device_resp.status_code == 200:
for device_json in device_resp.json():
device = "_".join(device_json["description"].split())
device_id = device_json["id"]
get_experiments(device, device_id, auth)
else:
print("Unable to pull state data. Status: {}".format(status_resp.status_code))
exit(1)

def get_experiments(in_device_name, in_device_id, in_auth):
experiments_url = "{}/{}/exps".format(__BASE_URL__, in_device_id)
experiments_resp = requests.get(experiments_url, in_auth)

if experiments_resp.status_code == 200:
experiments_data = experiments_resp.json()
seneye_data["nh3"] = experiments_data["nh3"]["curr"]
seneye_data["nh4"] = experiments_data["nh4"]["curr"]
seneye_data["o2"] = experiments_data["o2"]["curr"]
seneye_data["ph"] = experiments_data["ph"]["curr"]
seneye_data["temp"] = float(experiments_data["temperature"]["curr"])

if use_fahrenheit:
seneye_data["temp"] = float(seneye_data["temp"]) * 9/5 + 32

write_files(in_device_name)
else:
print("Unable to pull experiment data. Status: {}".format(status_resp.status_code))
exit(1)

def write_files(in_device_name):

path = rootDir + workDir
access_rights = 0o777

if not os.path.isdir(path):
try:
os.makedirs(path, access_rights)
except OSError:
print("Creation of the directory %s failed" % path)
exit(1)
else:
print("Successfully created the directory %s " % path)

for key in seneye_data.keys():
filename = "{}/{}_{}_data".format(path, in_device_name, key)
file = open(filename, "w")
if key == "temp":
data = str(seneye_data[key])
else:
data = seneye_data[key]
file.write(data)
file.close()
os.chmod(filename, access_rights)

get_devices()

exit(0)

Create a run file to make cron easier:
/home/pi/seneye/seneye.sh

#!/bin/bash

/usr/bin/python3 /home/pi/seneye/seneye.py >>/home/pi/seneye/log 2>&1

Setup a cron job to run twice an hour:
crontab -e

10,40 * * * * /home/pi/seneye/seneye.sh

Create file Drivers (Admin -> Drivers). Create one for each of the 5 parameters (NH3, NH4, O2, pH, Temp)
Path should be: /home/pi/ReefData/seneye/<seneye name>_<parameter>_data
ie: /home/pi/ReefData/seneye/92_Corner_temp_data

Create Analog Input Connectors for each parameter (Admin -> Connectors)

Add "pH" montors:
Under pH, add each monitor. Only poll every 1800 seconds due to Seneye only updating data 2x an hour.

Very interesting. Am I right to assume this require to have the web server too?

No, right now I’m using a mini stick computer to run the Seneye. I don’t use their SWS web server.

just found this...
first of all the rows i marked red is that pass and username for the pi or my seneye account?
any thing elese i have to change in the code to get it to work?

I believe that is correct

 

[Ranjib]

Wow , I was not aware of this . Very cool, thank you for sharing

 

[Krheigh]

I believe that is correct

Ok you believe what's right? I have two answers in my question... Both can't be correct

 

[Krheigh]

Wow , I was not aware of this . Ver cool, thank you for sharing

You should add this as a plugging direct to the feef-pi

 

[Krheigh]

well if someone get this to work...feel free to enlight me;Nailbiting

been banging my head to the keyboard all day with no results.

my coding skills is not that good
neither is mind reading...
followed the instructions above but get confused about the file paths... there's
"/home/pi/seneye" and "/home/pi/ReefData/seneye"

Create both directories.
/home/pi/seneye is where the code goes
/home/pi/ReefData/seneye is where the data will go for reef-pi to read

 

[Krheigh]

Sorry, Seneye credentials

could you please post a screenshot of the seneye.py file the code above doesnt work and theres seems to be missing alot of "tab"
blurr your logindata or send me a copy of seneye.py without login data.
