bleeding-edge-ranciliopid VS clevercoffee

Personally, if you want PID, I'd go https://github.com/medlor/bleeding-edge-ranciliopid with using a ESP32 (S3 if possible). Setting up system just for PID is super simple but then gives you options to expand functionality later on.

I'm basing it on a couple of things but for the main app/control software I'm using https://github.com/medlor/bleeding-edge-ranciliopid with an esp32 for the number of pins but also going to be referencing http://espresso-for-geeks.kalaf.net/features/pressure-profiling/ for the pump side of things.

Here is the version I used: https://github.com/medlor/bleeding-edge-ranciliopid with DS18b20. See row17 where you can select DS18b20 if you like. I never steam so DS18b20 works for me. https://github.com/medlor/bleeding-edge-ranciliopid/blob/master/rancilio-pid/userConfig.h.SAMPLE

The first image is a Rancilio Silvia espresso machine. If you like DIY, you can add your own PID with an ESP32 (wifi-enabled cheap microcontroler), a thermocouple (to measure the temperature of the boiler) and a solid-state relay (to turn on/off the boiler heating element) for less than $40. I did it in my own machine following this repo: https://github.com/rancilio-pid/clevercoffee. I have perfectly stable temperature, I can turn on the heating from my bed (with MQTT and HomeAssistant) and I used the occasion to fully understand how my machine works (which tbh is always a big part of the motivation for doing these kind of projects).

I'm very interested in doing the same PID mod. Did you follow any instructions besides this one on GitHub?

By the way you can also access the site through https://clevercoffee.de/. The source code and useful information can be found in the github repository: https://github.com/rancilio-pid/ranciliopid

I am using ranciliopid which already does some of the things you mentioned:
