It looks like it's no longer available, but we have this one paired to our Smartthings hub, and it works great: https://a.co/d/0aHfZi76 This appears to be the suggested replacement: https://a.co/d/0gxFHxJk You can always use the old(er) school mechanical timer, if connective is not important: https://a.co/d/0ek5ey0s For those naysayers, we have our water tested pretty regularly for health concerns, and never have any type of issues. We have it set from 0500 - 0730, then again from 1630 - 1900, daily. The one we have records energy usage in the Smartthings app... When we have company staying with us, we turn off the schedule and just let it run. Those times, we see about a 60% increase in power consumption. I've done the math several times, and this saves us ~$30/month off our utilities bill. It is an older Rheem 90 gallon. In out prior home, we had to replace our heater, and went with a connected Rheem. I wasn't a fan of their integration, and find the (above) switch method much simpler to use and control.
