Not sure how many of you are using Node-RED, but the other week I replaced my STC-1000 controller with Shelly hardware + some software I built for Node-RED. Since then I've packaged that logic into a node that anyone can install and I've complemented that with some additional nodes that now allows for fully automated multi-step fermentation.

If anyone is interest, I made a write-up on how to get started. Would love some feedback/suggestions on the project and would ofc be fun if someone wanted to tag along and help me improve it.

A fully working flow, with Shelly and iSpindel integration could look something like this.

There's still some work to be done in how to conveniently provide a schedule to the fermentation controller. Right now, I'm just passing in a JSON through the inject node "Set profile" and that needs to be sorted out eventually ofc.

Anyway, if this is of interest to anyone, let me know what you think and again, if you have suggestions or comments I'd love to hear.
 
Interesting way of doing it. You could add home assistant to the mix which would let you create a UI, keep history, etc and still use nodered for control.

I've seen that you can combine Home Assistant with Node-RED but haven't done it myself. I use Node for all things home automation, including UI which it does have support for. Not sure how it compares to HA though.

For history I use InfluxDB and for graphing I use Grafana:

But I understand it's really not straight-forward to get started if you have zero prior knowledge. That's why I want to explore building a setup script that would take you from an empty Raspberry Pi to a fully functioning setup in just one single command.
