Kettle configuration and use

Brautomat32 supports up to three kettles.

• Kettle 1 (required): MAISCHE / IDS

• Kettle 2 (optional): SUD / MLT

• Kettle 3 (optional): HLT / NACHGUSS

Each kettle can be configured either as:

• GGM induction hob

• relay-based device (including webhook support)

Kettle configuration

All kettle parameters are described in:

• Basic setup

• Kettle parameters

Kettle Control Commands

A control command is detected by a colon in the step name:

DEVICE:POWER

Examples of valid device names:

• MAISCHE or IDS

• SUD or MLT

• HLT or NACHGUSS

A custom kettle name from settings can also be used.

POWER can be:

• number 0..100

• ON (=100)

• OFF (=0)

From version 1.60, power at boil transition can also be set with special commands:

• IDSTHRESOUT:80

• MAISCHETHRESOUT:80

Option 1: Manual Kettle Control

Kettle 2 and kettle 3 can be switched manually via their power buttons in the web interface. Example: configure NACHGUSS target temperature to 78°C and switch it on when needed.

Option 2: Automatic Kettle Control via Mash Plan

Kettle configuration

Example in line 2:

• HLT:100

• target temperature 78°C

• duration 0 minutes

Result:

• NACHGUSS is switched on at 100%

• target temperature is set to 78°C

• Brautomat moves immediately to the next step

• NACHGUSS stays active and PID controls it in the background

Equivalent commands:

• HLT:100

• NACHGUSS:100

• custom kettle name, e.g. COOKER:100

Kettle configuration

Another example:

• SUD kettle is enabled with 100°C target and 15-minute duration

• Brautomat stays on this step until target temperature is reached and the 15-minute rest is complete

• then SUD is switched off and the process continues

If the value after : is not numeric and not ON/OFF (for example SUD:Cook partial mash), Brautomat interprets it as 100%.

Example: Dynamic Power Adjustment

You can adapt power during the process. If your induction hob has 3.5kW and your kettle is small (for example 20l), use MAISCHE:75 to reduce maximum output and avoid aggressive heating.

Typical setup for this kind of command step:

• target temperature: 0°C

• duration: 0 min

• autonext: enabled

Example: Decoction

Without explicit command, mash steps always run on kettle 1 (MAISCHE). With command steps, you can control additional kettles. See also: Mash plan functions.

Decoction workflow example:

1. Move remaining mash into kettle 2 (manual step, autonext off).

2. Keep kettle 2 at temperature (duration 0, autonext on).

3. Boil partial mash in kettle 1 (autonext on).

4. Merge mash back (autonext off).

Practical principle in multi-kettle setups:

• boil partial mash in kettle 1

• hold temperature of remaining mash in kettle 2/3

• run NACHGUSS on kettle 2/3

Webhook

To use webhook controls:

• set PIN white relay to -

• configure webhook URL and switch mode

webhook

Example Shelly 1PM:

• ON: http://192.168.1.5/relay/0?turn=on

• OFF: http://192.168.1.5/relay/0?turn=off

Webhook base URL:

http://192.168.1.5/relay/0?turn=

Set webhook switch parameter to on/off.
