I have a B-Hyve XD Bluetooth 4-Outlet Hose Faucet Timer and it seems to work OK as long as the battery level stays above 85%. Below that it starts getting flakey: not running programmed schedules, not responding to the app, etc. I have a couple of hubs plugged in around the house, but that doesn’t seem to make any difference. Usually one set of batteries lasts me the entire season, but I’ve already been through a couple of sets. I was wondering if using something like Energizer Lithiums would get this thing through a whole season. Considering all the timer does (Bluetooth, WiFi), it seems like two dinky AA batteries isn’t enough.
