I’m having the same poor experience with my Rachio 3 (12 zone). This irrigation controller falls off my WiFi at approximately the same cadence as my lawn is actually getting watered, so I’m finding that I can’t trust it. I’d be curious to know if the Roaming assist feature on my router (i.e., to disconnect clients with RSSI <-55dBm) is involved, but alas the “troubleshooting” Rachio component in iOS isn’t designed to surface any useful information. It’d be nice if I could just hit the device at port 22 and do some real diagnostics, or if it had an ethernet port.
I’m not going to invite RouteThis to sniff my network. Also, the fact that Rachio claims router MAC address filtering is “not supported” is beyond frustrating. Does the MAC address change with each reboot, like code-rolling on a garage door? UPDATE: the MAC filtering is supported in Step 5; the Rachio guidance is just phrased badly in Step 3.
There are some silly engineering assumptions here (e.g., that an iPhone and the Rachio controller will talk to each other over wifi, or will be switched to each other L2, or that RouteThis is allowed) that are unfortunate.
If I find a reliable solution, I’ll post it.
