BBQ automation

[emielstroeve 22]

hi all,

 

I'm looking for a setup to automate the BBQ. The temperature on my bbq can be controlled with the amount of air going in the heating system. More air means a higher temperature.

 

Just for fun I would like to automate this, there are dedicated systems to do just that, but I have Fibaro! 

 

So what I need is a temperature measurement in the BBQ, I have some thermometers who probably work with an NTC resistance. I think I need a fibaro dimmer to measure the temperature, this is the biggest problem. How can I connect the sensor to the dimmer inputs an measure temperature? 

 

Once I've got the temperature, I think it's easy to setup a smal fan blowing into the air inlet of the bbq, depending on the wanted temperature and the actual temperature.

 

any thought or experiences with this 'lazy-bbq' setup?

 

cheers

@emielstroeveCheck out the CyberQ, Stoker or Flameboss. These are all wifi connected BBQ temperature controllers. They come with a temperature sensor for the pit and up to three probes to measure core temperature. You set a set point for your temperature and the fan controls the rest. I have been using the cyberQ Wifi for several years now with my Big Green Egg and this works like a dream. I once made a beginning with a VD. Currently have one that gives me the status, but does not give any control. Will finalize this one day...

thanks for the guidance, guys.

 

but I really would like to use fibaro stuff to get this going. all I need is how to connect a ntc thermomter to a fibaro dimmer input and read the temperature so I use it in a scene.

Fibaro dimmer does not have analog in. Might work with RGBW (and some other brands' modules), it has analog in and a pullup to slightly above 10 V (around 18k I think), so you could try to connect the ntc to IN and GND and get a voltage reading on your controller. Then use google to find the formula to convert to temperature, What is the ntc resistance at room temperature?

 

Edit: ntc is ok up to 125 degrees C. If you are not sure about the specs, but it can handle higher temp, then your probe probably is a k-type thermocouple and you need a converter or a different solution...

agree, I mixed up the dimmer and the rgbw, I meant the rgbw. I'll try the setup and see how far I can get
