Disclaimer: I am not a developer by any stretch, so forgive my ignorance when it comes to the structure. This is also a work in progress.
Updates as of 8/23/2024: I have the majority of the hardware working. I keep running into bad chips, but that just means I'm adding additional options when it comes to the sensor types. So far I have included support for the following:
- MAX31856 - I'm using this with a K-type probe
- MAX31855 - I might have fried this one when testing the K-type and since swtiched to the 31856 which I think is more versitle.
- MAX31865 - I scrapped this because although I initially was going to use RTD (and still might for some things) I wanted to get the K-type working first.
- ADS1115 - I haven't wired this one up yet, but I'm going to use it with the standard meat probes that use the 3.5mm jack
- Personalization settings - While I was waiting on hardware to arrive I added the ability to personalize the nav, buttons, and background.
- Sensor CS Pin usage - When adding a sensor you can select the CS pin only if it's not in use. Had to include some guardrails of course.
- Ability to edit the config.yaml file from the settings page. I did this as a convenience at first, but I'm leaving it because it's served useful in troubleshooting.
Next on the roadmap:
- I've been having issues with the modals appearing right. There's a background behind them and I can't seem to find what's causing it. It's not a functional problem, but an annoyance.
- I broke the chart when I started working on the settings portion of the app and I want to come up with a way to add/remove charts with the addition or removal of new sensors/probes.
- Adding a probe section that can tie into the sensors. Some of the sensors (ok, amplifiers) can support more than one probe and I need to account for that. My goal for now is to get this working with one sensor/probe and go back to the rest.
- Something to conrol the damper. I want to be able to open and close a damper that I'll install so I can mitigate flame ups, or to shut the system down in an emergency situation. Once I get through the temperature stuff I'll get back into this.
RPi controller for Masterbuilt gravity fed smokers
This is a work in progress and inspired by Nebhead's PiFire build for pellet smokers: https://github.com/nebhead/PiFire
Initially I was going to branch from his code, but after reviewing it I determined there are too many differences with the gravity fed line of smokers vs. the pellet ones.
The idea, however, is to build a replacement controller for my Masterbuilt 1050 smoker since the original one broke. I have aspirations of doing the following:
- Allow for 5+1 temp probes - 1 probe for grill temp, 5 additional for meat.
- Fan control - this is similar to the existing setup by Masterbuilt. Turn the fan on if temps get lower than grill target, but use PID and allow for autotune... maybe
- Damper control - The smoker has two dampers that are intended to be used to suffocate the fire from the gravity fed charcoal/wood box. I intend to add motorized dampers to automate this at the end of a cook, but also as a safety measure for flame ups.
- The controller will have both an SPI touch panel display with rotory encoder as well as a web dashboard.
