Smart switch - no neutral needed (EU)

I would like to ask if someone can advise me some hardware solution for my situation. I have older house without neutral wire for light switches. Exist smart switches with no neutral needed (for EU )? I finded one by Xiaomi but it is only for square boxes (China etc). Fibaro Dimmer 2 can work too, but I need control light in 10 rooms and this solution is little bit expensive. Thank you for any advice

It can be done with sonoff using capacitors!
