Hi All,
I’ve want to setup a z-wave automation and I have done a bunch of searching and so far I haven’t been able to find an approach that will accomplish what I want. I’m hoping someone on the forum know of a device/control methodology that will allow me to accomplish it.

I have a solar water heater on my roof that typically heats my hot water to a comfortable temperature most of the time. However, we get a lot of rain/overcast skies here and when that happens the water doesn’t heat up. Usually the first indication of this is when you step into the shower that night :o resulting in the 30 second cold shower dance.

In order to avoid scenario 1 above one needs to step into the garage, check the in-line analog temperature gauge on the water heater, (see attached photo) and if it too low flip a switch on a timer box, (see attached photo) to turn it on. Of course one has to remember to do this on days when the solar heater doesn’t do it job or one again gets to do the 30 second cold shower dance.

What I want to do is A) Replace the timer box with one that is z-wave controlled, (this part is easy) and B) Replace the in-line analog gauge with a Z-wave temperature monitor, (not so easy in that I can’t seem to find such a device).
I can use this to replace the timer box
But I can’t find anything z-wave that will replace the in-line analog temperature gauge
The goal is that the Z-wave temperature gauge sees that the hot water temperature drops below xxx degrees then it will kick on the water heater, once the water temperature reaches xxx degrees or above then it will turn it off. Hopefully this will prevent the cold shower dance and save some energy as sometimes when you turn on the water heater you forget to turn it off so it keeps running long after one’s shower is done.
Also, I’d like to try and do this without spending a small fortune as my accountant, (wife) wouldn’t like it.
Thanks
Gordon
