Setting up in the UK

Hi, I hope I’m posting in the right place, but I’m new to the forum, so thanks for having me first off.

I’m new to irrigation and have recently laid my system outside and connected it up to an Antelco Ezyvalve4 box. I’m researching controllers and love the Rachio 3, but I’m in the UK. I understand why they aren’t selllung into Europe at the moment, but wonder if anyone has set one up in the uk? Any problems or things to share that I should consider? And any recommendations on 220v/120v converters?

Many thanks,

Greg
