Where are you based I will book a flight 
Auburn Washington
I have a friend that lives in Australia and he pops in 2 to 3 times a year.
he comes to visit his son who lives here, but spends more time at my taproom!

I am in Australia - and am about to book a flight !!
I would suggest that you have something completely independent of NR that could perform a master off type function and acts as a supervisor to the system - in my mind something like a Tasmota TH16 that monitored all the temps - independently of the other systems - running say Tasmota with Rules - so no Node Red involvement - simple rules - like if Temp > xyz (safe limit) - generate an alert and shut down a master ssr that shuts off everyting if it does not hear from someone in X period of time
Its all the edge use cases that you do not think of that come back and bite you - i have had instances where my boiler (gas) for hydronic heating - stopped responding to on/off commands - but only in a very weird combination - so i was pushing solar heated hot water (much lower temp) into our buffer tank and the Gas boiler was trying to raise this to some ridiculous temperature. All because of a power failure and then a WIFI access point not starting up correctly
Craig
I definitely agree,
Ok i searched for the Th16 and all i get is freaking plug in outlet crap from Amazon
...can be flashed to Tasmota, of course (you should do, in order to get rid of the chinese cloud and enable the same functionality as with your wroom)
Edit: the TH16 has a 2.5mm Jack Terminal to connect with the standard (single) wired sensor. In order to be able to upgrade, you need something like this (I think it is a 4 pole jack): https://www.amazon.com/Conshine-4-Pole-Stereo-Terminal-Connector/dp/B076NGDR7Z/ref=sr_1_1?crid=RJMNBUCXNEP6&keywords=2.5mm+jack+screw+terminal+4+pole&qid=1649748985&sprefix=2.5mm+jack+screw+terminal+4+pole%2Caps%2C202&sr=8-1
ok im thinking outside the box here.
if i was to loose wifi to an esp8266 that means i have no temp going to node red.
thus i have no temperature control.
i have 3 temp controllers hooked up to the fermenters now.
i should have an if in the tasmota esp8266 that if no internet connection it closes a circuit on relay wich supplies power to the back up temp controller.
kepping the beer in a fail safe till internet comes back up.
im assuming it would have to be wired in a way like a dual switch for a stairway.
one switch at bottom and one switch at top
both control the same light.
so you can turn on when walking up and then turn off at top when not needed that time of scenario.
whats your thoughts.
Also should i change my topic name. i know it when a good distance and we have addressed plenty of issues. But have added others.
im working on a comment that walks through what was actually done to aid anyone else trying to do what i have been doing.
First and foremost.
Thanks to these Friends for all the help.
@dynamicdave, @Hominidae, @craigcurtin, @smcgann99, @zenofmud, @Zodiac-69, @jbudd,
@tonylane26, @markost, @hotNipi,
Names are not in any special order other then in order of when they stepped in to help.
So my basic initial question was I need help getting all my Ds18b20 temp sensors data sent to my node-red with mqtt and an ESP8266. I have very little programing knowledge.
If you have programming skills these links will help you a bunch.
However, I have verry little Programming Knowledge, so I was suggested to use
Something called Tasmota
Very amazing utility, or āUIā for the EsP8266
Please read the material about it and about how to install.
I will share a few links here that will help you.
Read this well depending on what you really need you can download the proper bin file for your solutions. Thus leaving space by not downloading an enlarged bin file.
another option is ESPEASY
I ended up using Tasmota and I love it.
there is an online flasher option but that didnāt work for me I used Tasmotizer to flash my esp8266ās
once you have the esp8266 flashed you can go in and mess with your settings.
The biggest thing you want to also install on your computer is mqtt utility called
āMqTT Explorerā
You can read and download it here.
it will make it easier for you to know your topic id from the esp8266
making it simply to subscribe to it from the node in your flow.
Now when you have the temp sensors going into your node they are going to be a big message
In Json format. You can opt to parse the Json file and then that splits them up.
I did in order. Gathered message from mqtt, then parsed into objects.
Then I split the objects up
I then had to push my Temperature to be my msg.payload
here is the flow that handled the MQTT message

Now everything is working for what I needed however im now working on the temp control side now that my temperatures are reliable data!
Further note. You can in Tasmtoa change the Temperature display preference.
In tasmota console type command : āSetOption8 0ā or āSetOption8 1ā
Show temperature in
0 = Celsius (default)
1 = Fahrenheit
This obviously isnāt a detail how to but these are the steps I did to complete mine.
Guys if I missed anything please chime in and ill edit this.
Cheers to all

as said, use the Rules feature in tasmota.
As a coincidence, someone just asked for such a solution in the tasmota group: https://groups.google.com/g/sonoffusers/c/x-guuXdQAec/m/Kz_tolnCBAAJ
....thanks for writing up your project log as a solution....nicely done.

Thanks, i joined that group as well, cheers
Yep be good to add the following console commands in Tasmota
Timezone
DST
Teleperiod
Rules and Timers are also two other valuable things i use in Tasmota
Timers as failsafes for relays - so my pool pump is controlled by Node Red through Tasmota - but at 5PM every day i have a Tasmota Timer set to turn off the pool pump - in the event of issues with my remote control of the Tasmota switch i have a failsafe to turn the pool pump off before Peak hour starts
Craig
I just take one of the Sonoff standard DS18B20 with the jack on it and cut the cable and then use that as a pigtail
(But nice find with the 4 pole jack)
Craig
so what do you guys use software wise to plot out your electronics for wiring.
i can always draw on graph paper but no-one will understand my crazy mind not even myself lol
I use Fritzing - loads of functionality for very little outlay.
It produces very nice breadboard layouts.
It has loads and loads of component library parts.
Here's an example...
ok got it.
now nexed silly question.
according to tasmota docs
SwitchMode 2
Set switch to inverted follow mode ( 0 = ON , 1 = OFF )
At the time when the circuit is closed, Tasmota will send OFF and opening the circuit sends ON .
if i need an active low to "activate the relay" then i should use this correct?
im assuming the 0 = low and the 1 = high
Sounds about right
Just a thought but unless you going for the longest thread record you may want to start new posts for next questions
ok valid!
was just brain storming. on it.
You are in 7th place BTW 
well i need to fix that lol
