Ready in” stuck at -1d -1:00:00 despite correct ambient and target temperature #911

Hi, and thanks for a great project.

I’m experiencing an issue where the “Ready in” value is always stuck at -1d -1:00:00, even though I’m providing valid values via MQTT and the module is otherwise working as expected.

What I’ve tested:

I send the following payload to layzspa/command using Home Assistant:

{ "CMD": 15, "VALUE": 14.2, "XTIME": 0, "INTERVAL": 0 }`

This correctly sets the ambient temperature. I can see the new value reflected:

In MQTT Explorer ("AMB": 14)

In the Lay-Z-Spa Module web interface (Ambient Temp: 14)

I’ve also manually changed the target temperature (e.g. -40°C) in the web interface and made sure the heater is running.

The problem:

Despite valid values being set, the “Ready in” field still shows -1d -1:00:00 and does not update.

I’ve also tried:

Restarting the module

Re-sending the ambient temperature value

Changing values directly in the web interface

Nothing seems to make the “Ready in” value work.

Additional information:

The MQTT connection is working correctly

The module status is “Alive”

All values appear correct, except for the “Ready in” time

Earlier, I tested setting the ambient temp to -40, but have since sent valid values
