Hi, New to Rachio but not new to automation. I have been looking to drive some accuracy into my device with a flow sensor. Unfortunately I was not educated enough on the gen’s to know the difference before I bought a gen 2. I really don’t see a reason to rip it out and upgrade to a gen 3 for a flow sensor that’s reasonable priced. I see quite a few sensors that are pulse-based that are for sale well below the $250.00 mark that might work for my “new” gen 2. Is there a spec for wired flow sensors that shows compatibility? I see some have bashed Rachio a bit for being under-handed and not supporting more in order to drive the newer product… I’m betting that’s not the case. Any help?
