Use a digital input to call the /startmash and/or /proceed endpoints #2

It would be quite handy to tie a Spark digital input into the automation, allowing for a button press to start the mash automation, and continue the automation from a pause

fdewasmes commented 2 years ago

in fact, there is already an API call ready to resume. When you are talking about a digital input, do you mean a physical IO?

astephon88 commented 2 years ago

Correct. I have a push button on my control panel that I could connect to a spark 4 GPIO pin configured as an input, and would like to be able to use that to start/resume the automation

I know Elco was planning to have this kind of small automation directly in the spark itself together with a piezo alarm. I asked him a few days back but didn't receive an answer and I'm not sure this is high in his priority list. I think this is the kind of automation that could be easily and properly handled using the embedded Node-red as I guess digital input raises a message on MQTT. Am I right? If you can provide me with a payload sample I could try to setup a node red schema for this.

I haven't seen any documentation for the digital inputs, and I haven't received my spark 4 yet, so I don't have an answer there. I was envisioning this "resume via digital input" feature as being an optional part of the brewfather automation itself (i.e., you specify what service/pin to use as the resume with a parameter in the compose file, and if specified, the automation will monitor the input for events and act accordingly). But if you don't think that's appropriate, I can look at writing a separate service, or using node-red. Are there any examples of using node-red with brewblox? I've only seen it mentioned in the design decision document about deprecating the automation service.

So, this might be a moot point for now. I just got my Spark 4, and I don't see any way to configure a pin as an input. Maybe that hasn't actually been implemented yet?

fdewasmes commented 2 years ago

Normally you should be able to configure it this way but this may not be available on the UI yet. Have you tried to contact them on Discord?

fdewasmes commented 2 years ago

I can surely make an update to have automation resume using this input pin. I think this is useful for anyone.

astephon88 commented 2 years ago

Just asked on discord. Elco said that's what he's currently working on, so it's not available yet. Sound like he's trying to wrap his head around use cases, so I pointed him to this issue.
