…and to make matters worse - the new Rachio 3 uses the 900Mhz band for communication with the flow meter. Unless it is a very specific window in that band, it is illegal to use it in Australia. Vodaphone have licence that band and WILL find you if you have a device operating in their spectrum. You will get a cease and desist notice first and if you don’t turn it off, you WILL get a hefty fine.
So Australians - DO NOT BUY THE Rachio 3 under any circumstances!!!
If only they had used the 433Mhz range, the device would be legal worldwide!
Sad to have such a capable device not available to Australians because of a small mistake.
