Monitoring Grill Temperature (is it hot)

Post by scyto » Mon Mar 15, 2021 12:25 pm

I have never used the temperature sensor function on the gem.

Is it possible to use a high temperature RTD to monitor the temp of my grill (it doesn't need to be super accurate - just want to know if i have left it on!)

If it is possible does distance matter? I would need to run a 100ft back to the GEM would that represent an issue?

Installing a Dallas 1 Wire (DS18B20) for a single 100 foot run won't be a problem. The sensor offers a range from -40'C ~ 125'C / -40'F ~ 257'F and has an accuracy of 0.5+/-. 22-4 alarm wire can be used to make that run with no problems . . .

Thanks!

Any experience of using https://cdn-learn.adafruit.com/download ... 31850k.pdf - while not drop in replacements these can talk the 1-wire protocol and allow any k type thermocouple to be used.
I guess ben would need to weigh in?

We don't have any plans to add any more sensing to the GEM. The timings are pretty tight to get all 8 sensors reading (and the same process is used to read pulse counters).

You could piggyback off the WeatherFlow stuff if you want to put something together. There's a script running absorbing all the UDP information the devices put out.

https://weatherflow.github.io/Tempest/api/udp/v143/

The obs_air packet is what you'd have to reproduce.

We may make a generic webcall to inject temperature values eventually.
