The relay with white LED supports 20 Valves. It also supports Apple Homekit.
I also have the old relay with blue LED and limited to 5 valves which is very disappointing.
This means, even if my blue led thermostat indicates 0/20, I could only connect 5 valves?

no, you can install 20.
Only the first 'blue led' batches that were produced are limited to 5.

The LED is no good indication, use the app to check!

What do you mean "first blue led" batches that were produced are limited to 5 ? A newer "first blue led" batches are supposed to handle 20 ?
This means I have an "blue led" which was produced in 2nd way, as my app shows 0/20 ! Good then!

It's not a bug.
Some of the Thermostats with a blue LED relay can control up to 5 Valves, and some can control up to 20 Valves.
It means some of the blue ones can control up to 20 and some of the blue ones can control only up to 5....can I relay on what is written in app? (I have blue one led and it shows 0/20....so?)

Yes, correctly.
And yes, the app shows the correct number of valves your relay supports!

Hi all,

I seem to recall that you can tell by the serial number whether the Thermostat can control up to 20 Valves.
Has anyone got any more information on that?

(I need to replace my 5-valves Thermostat with a preferably secondhand 20-valves one...)

Just press the button on the Relais. If the led is white and not blue, it supports 20 Valves.
