Group member not switching using blockly

[Shade]

Hi,

I have a group containing 4 members: 3 Hue lights and a Kaku switched lamp.
When I manualy switch the group on or off, all lights respond.
However, when i use blockly to turn the group on or off, all the Hue lights respond, but the Kaku switched lamp does not.
The problem is consistent; manual always succeeds, blockly always fails.
The blockly is really simple, just a dusk sensor as a trigger and a user var to prevent flapping (the var is reset daily in another script).
Anyone got a clue?

Sometimes the KaKu signal is not picked up by a device if too many signals are send at the same time or shortly after each other.

For both (manual and Blockly controlled); what do you see in the log?
Can you also try to switch the KaKu also as individual device in the Blockly?

To improve Kaku reliability I implemented this LUA script:
viewtopic.php?t=16933
I've set it to 2 additional events, so the signals are transmitted 3 times in total.

Today the dusk sensor activated at 18:20 resulting in the following entry in the domoticz log:
2020-09-25 18:20:01.354 Status: EventSystem: Script event triggered: 433MHz reliability

When looking at the Kaku switched lamp log this is confirmed with:
2020-09-25 18:20:02 On EventSystem/433MHz reliability
2020-09-25 18:20:02 On EventSystem/433MHz reliability
2020-09-25 18:20:01 On EventSystem/Woonkamer lampen aan_1

The same goes for activating the group manualy : the LUA script is triggered and shown in the eventlog.
The logging is exactly the same except that the Kaku signal is not actually send when triggered by blockly.

Last week I migrated my Domoticz setup from my nas to a dedicated raspberry pi. That made no difference, the behaviour was still the same (although I did import the db from my nas, so the problem may have been copied as well).
Also made a seperate blockly to switch the kaku lamp, but it makes no difference.
One last thing I can think of is that the kaku switch is very old. It still uses the ARC signal in stead of the newer AC signal. Think I'm gonna try to get a newer model.
