Thank you for your reply Prunt,
I use a Synology AC2600. It is an amazing router and will let you do pretty much anything you want. You can turn 2.4 or 5 GHz bands on/off. You can assign more bandwidth to individual devices… etc etc etc anything you could want…
The Synology router, on it’s own, has connected to the Rachio controller on the 2.4 Ghz band without my intervention… I’m using this router in “smart connect” mode where it does all that for you automatically. I’m having no issues with over 30 smart home devices throughout my house from various manufacturers. This is one of the main reasons I bought the Synology router.
I would prefer to use the Rachio3 as Rachio says it can be used. This is from the Rachio router requirements page:
Rachio controllers support both dual band and single band routers ; a steady 2.4 GHz connection on a secured (WPA/WPA2) network is required for Generation 2 and Generation 1 controllers, but Rachio 3 can use either 2.4 GHz or 5 GHz connection on a secured network.
This is not a BIG deal for me… Since adding the Rachio to Homekit is really limited in ability, (Other then saying “Hey Siri, water my grass” as my wife or grandkids are walking / playing in the yard), I would rather just use the, far more capable, Rachio App for now anyway…
I understand Rachio is working this problem and since they have to work with Apple on this, I can only imagine the difficulty that brings to the table.
I’m going to wait for Rachio to sort out the problems and do it right.
Having said all that, IT SHOULD WORK and your suggestion is definitely one that I had considered and is the issue that Rachio needs to fix in my opinion
