Oven Monitoring System

Hi Guys. I am seeking some advice. I am working on an Oven Monitoring System that consists of 12 separate ovens. 4 of the ovens will have 6 RTDs, the other 8 will have only 1 RTD. I also need a temperature readout at each oven, indicator light, buzzer, and timer-start button.

My though is to use one ESP32-Pi+RTD Hat+ IO Hat + LCD hat per oven. All of the ESP32-Pi cards will be networked via ESP-NOW to a master system for datalogging. Any thoughts? Is the ESP32-Pi an easy solution for this?

I am very open to other solutions! Many thanks.

From the hardware staindpoint, it seems you nailed it. The I/O Hat should be 4-Relays/4-Inputs, which can do your indicator light and buzzer, and an external start button. You can use also the on-board pushbutton on the RTD or 4-Relay card, if this is acceptable mechanically. Alex might give some input about the software.

Hi,
Considering the ESP32-PI is actually an ESP32, do not see why you can not use ESP-NOW.
We are in process of making Arduino libraries for all our cards so the RTD HAT and 4-Relays/4-Inputs libraries are not ready. We will give them high priority if you decide to use them.
Let me know if you need more info.

Hi,
The RTD card library is ready. Has been published but will take few hours before you find them in the Library Manager.
Until then you can do a manual install, instructions here.

Both libraries are available in the library manager so you can search for SM_4REL4IN and SM_RTD and install the libraries. Checkout the examples, and if not cover all you need to implement, please feel free to ask.
