display multiple sensors on webpage python flask jinja

[pascale]

Hi,
I am a bit stuck,There are plenty of tutorials and forum replies for one DS18B20 sensors but I cannot find any for multiple sensors that dont use esp826 or something else. My code (below) displays the temperature of 11 senrors in the console, but I am stuck with display more than one on a web page. i have seperated my code into different modules to keep things clean and so I can import them as I need, The first is nested dictionaries with the 11 sensors

sensorsID = {
    1 : {'name':'top Cylinder','ID': '28-020f92456b1b'},
    2 : {'name':'Middle Cylinder','ID': '28-000398430420'},
    3 : {'name':'Bottom Cylinder','ID': '28-03170017b5ff'},
    4 : {'name':'Boiler output','ID': '28-0212924519b0'},
    5 : {'name':'Boiler Input','ID': '28-000798430de0'},
    6 : {'name':'Kitchen Output','ID': '28-0202924581e6'},
    7 : {'name':'kitchen Return','ID': '28-02169245238b'},
    8 : {'name':'Back Area Output','ID': '28-0317000e43ff'},
    9 : {'name':'Back Area Return','ID': '28-0317003f1cff'},
    10 : {'name':'House Output','ID': '28-0416c4a3a0ff'},
    11 : {'name':'House Return','ID': '28-021692451c79'}
}

the next is the code to read these sensors,

def read_sensor(sensorID):  
    tempfile = open("/sys/bus/w1/devices/"+ sensorID +"/w1_slave")
    thetext = tempfile.read()
    tempfile.close()
    tempdata = thetext.split("\n") [1].split(" ")[9]
    temperature = float(tempdata[2:])
    temp_sensor = temperature / 1000
    return (temp_sensor)

the next is the code that works in terminal

from mySensorModule import read_sensor
from mySensors import sensorsID
import time

for sensor in sensorsID:
    print("The temperatue of ",sensorsID[sensor]['name'],
            " is ",read_sensor(sensorsID[sensor]['ID']))

But the problem arises when i try to display this in a webpage, I can display one sensor but not all, Here is the code I have tried but I get an error; sensors.py

from flask import (
    Blueprint, flash, g, redirect, render_template, request, url_for
)
from werkzeug.exceptions import abort
from mySensorModule import read_sensor
from homeHeating.auth import login_required
from homeHeating.db import get_db
from mySensorModule import read_sensor
from mySensors import sensorsID
import time


@bp.route('/sensors')
@login_required
def sensors():
    for sensor in sensorsID:
        name=sensorsID[sensor]['name'],
        temp=read_sensor(sensorsID[sensor]['ID']
        
    templateData = {
       'name' : name,
       'ID' : ID
       }
        return render_template('sensors/sensors.html', **templateData)

Error:
File "/home/pi/heating/homeHeating/sensors.py", line 20
    templateData = {
               ^
SyntaxError: invalid syntax

this code is an adaptation of matt richardsons tutorial the html script looks like this;

{% extends 'base.html' %}

{% block header %}
  <h1>{% block title %}Sensors{% endblock %}</h1>
    <a class="action" href="{{ url_for('sensors.addsensor') }}">New Sensor</a>
{% endblock %}{% block devises %}
  {% for sensor in sensorsID %}
    <p>The {{ name }}
    the temperature of {{ name }} is {{ temp }}
    </p>
   {% endfor %}
{% endblock %}

if I use the origional code with this template no sensors are displayed, I hope you are able to follow this! Any help is needed.
