Digital Actuator Channels


I am setting up my new Spark 4 with a fermentation fridge, and I am running into some difficulties. When using the Wizard, I am not able to progress beyond the selection of temperature sensors. I get a “no entry” icon when I try to click next. I have then gone to setting it up manually, but I am not able to access the channels on my DS2413. When try to open the “advanced” dialogue on the Digital Actuator, I get a blank screen. And when I look at the Digital Actuators they, quite rightly, state that no channels have been selected.

What am I doing wrong?

Thanks and regards,

If you just updated, have you also reloaded the UI?

In the wizard, during the hardware selection step, if you create a Mock Pins block, can you select the channels from there?

I have reloaded the UI a few times since. Wrt the Mock Pins, then I fail to create the block. I get the response: Error: Request Failed with status code 400.

Regardless of the Mock Pins block creation, I still cannot proceed beyond the fourth screen in the Wizard, the “Assign Hardware Blocks” step.

I have looked at the Digital Actuators setup on my Spark 3 wit functioning temperature control, and here I am also seeing a blank window when I go to the advanced settings.

Could you please run brewblox-ctl log ?

In the UI, could you please recreate the 400 error, and then export the UI logs? (Admin page → system → debugging)

I have run brewblox-ctl log, final line says it has been uploaded to

Attached is the debugging file.

brewblox-logs.json (322 Bytes)

There should be a URL to, where the log is viewable.

Yes, sorry missed that:

It looks like you’re still running an older version of the software. To fix this, run brewblox-ctl update.
Be aware that the update also includes a change of databases, that requires running a migration command.
The output from update will tell you what commands to run.

Hi again, did the update, but the problem persists

Quick update. I have done a couple of refreshes of the UI, and now there appears to be some changes. The Wizard still doesn’t work. I will try the manual build and get back to you.

In the admin page, (system → debugging), what is the UI build date?

Sorry for the late reply, reality took over. The build date is 2021-10-14T11:10:00.467Z.

I have built the temperature control for the fermentation chamber manually and everything is working as it should, apart from the Wizard but that is not so critical now for me.

The wizard should be fixed now.
