The Rachio3 supports the discontinued Wireless Flow Sensor via a wireless transmitter that uses a frequency that is illegal to use in nearly all of Europe. It comes with a US only power supply and it will likely have a WiFi chip that is intended for use with US WiFi frequencies and permissible signal strengths.
Until Rachio do a new version of the Rachio3 specifically for other markets arguably Rachio should be a lot more honest and actively discourage non-US/Canadian customers from buying this product because otherwise they are helping break various laws.
Now I said ‘until Rachio do a new version’. Well it turns out they have done a new version the Rachio 3e. Unfortunately Rachio have not that I can see stated whether any of these issues have been addressed. One would presume that since it was launched after the Wireless Flow Meter was discontinued that they will have removed the matching transmitter that supported that Wireless Flow Meter and therefore the biggest legal issue has been solved.
They could have spoken to their WiFi chip supplier and at the design stage ensured versions with US and EU compatible WiFi chips could be fitted. They could have similarly discussed with their power supply supplier about sourcing again both US and EU compatible power supplies.
Therefore the Rachio3e could have easily been readied for legal international sales. Sadly I get the very strong impression that Rachio have done none of this and therefore have made absolutely zero progress towards legal sales to International markets.
Whilst I totally sympathise with manufacturers who are starting up that moving from an initial product for an initial local market to products that address multiple markets takes time, cost and effort Rachio is now far from a brand new start up, have been repeatedly made aware of all these issues for many years and could by now at least with the Rachio3e had made these steps at negligible extra cost.
I am also extremely disappointed to see that the Rachio3e does not support HomeKIt.
I am therefore going to have to give up on Rachio and see if there are any other more enlightened firms with legal products, unless Rachio can share good news with us that they have taken these issues on board with the Rachio3e.
