Shelly Color Bulbs Enteties? or MQTT command topic

Configuration
, ,
1

I installed 4 colour bulbs (SHELLY DUO - RGBW GU10) in home assistant with ShellyForHass. The bulbs were recognised in ‘devices’ as SHCB-1. Unfortunately, there were no ‘entities’ made, so I couldn’t add the bulbs to the Lovelace-UI.
I also have Shelly dimmer 2 and Shelly 2.5 installed and they work flawlessly.

QUESTION: what goes wrong with the bulbs?

Therefore I switched to MQTT. I use the mqtt template that is shown below.
In the Lovelace-UI I can change colour, use white and effects, so that is fine.
The problem is: I can’t switch them off and on. (When I change the slider, within a second it’s switched back)
I use the topic:

shellies/shellycolorbulb<id>/color/0/set (command-topic)

and

shellies/shellycolorbulb<id>/color/0/status (state-topic).

According to the shelly API, I can’t switch the bulb with the command-topic …/set.
In nodered I can switch the bulb off/on with:

msg.payload = on (or off) and 
topic: shellies/shellycolorbulb<id>/color/0/command

So, it seems that I need a second command-topic: …/command.
In mqtt explorer I also see 3 topics: …/set ; …/status ; and …/command.

QUESTION: What should I change in mqtt template to switch the bulbs on/off? or is there another solution for this.
(yes, I put an RFXtrx switch in the light-rail to switch the power off/on for all 4 bulbs. But that is not an elegant solution)

Have you had any luck with Shelly bulbs? I’ve got a couple of RGBW2 GU10’s, and with the native CoAP integration i can get them to turn on/off and control brightness for White, but i dont have any RGB support?
