Looked around but haven’t come across any viable solutions for hot tub control…
I want to be able to turn my 220 VAC Hot Tub on and off completely.
I also want thermostat control as I normally turn the tub down a few degrees when not in use then bump it up a couple hours prior to use. This may be more complex considering the vast number of different hot tubs but then again I would think you would just be able to tie in a smart thermostat…not exactly sure how proprietary the control boxes are on hot tubs…
Anyone else done something similar?
Look forward to the different ideas out there, thanks!
I had a gutter heating system installed that runs on 220. As a solution, I had the electrician install a contactor switch (http://en.wikipedia.org/wiki/Contactor) to the 220 system, then a simple on/off switch is installed to the contactor. Doing so allowed me to use the GE z-wave on/off switch (https://shop.smartthings.com/#!/products/ge-in-wall-on-slash-off-switch). Not sure if this could work for your hot tub, but it may be worth checking it out.
Have you looked at this? http://smartenit.com/product/zbmlc30/ You will have to have a custom device type created to use it but it will control a 30A 220v load. That is about as big as your going to get in the home market. It is $179.
