Wifi / BT Dimmer for LED-filament bulbs

[Ramsing]

Hi.
I need some help on my project.
I want to build a ceilinglamp that uses 5-10 Filament/Edison led bulbs.
These look perfect, if dimmed enough for you to see the filament.
I use Amazon Alexa or Google Home to control most of my electric stuff in the house, but I have hit a problem in the planning.
I can not seem to find a external dimmer (don't want to replace switches) that can talk to my smarthome over wifi or BT and who can dim led´s without blinking or flickering.
I live in Europe where we use 220v, but that shouldn't matter as the dimmer sits behind the 12V transformer.
The house is old and I do not have a neutral wire.
Is there anyone here that has an idea how to solve this problem?
Im not an engineer or an electrician, but I know how to solder and have a basic understanding of electronics.
Any help, out of the box or tinkering with some Adafruit modules, is appreciated.
