[Hai-users] Looking for Hot Tub Control Ideas.

[neil collepardi]

Hi Brent.

I interface the Omni to an Jandy Aqualink (using serial ascii protocol)  
over one of the Omni's serial ports. There are many added features 
provided by that controller (ie salt controller, valve automation, solar 
levels, pool lite sync, temps, etc), as well as visual displays on the 
pool controller, that would be very difficult (if even possible and more 
costly) to be provided by the Omni by itself.      Interfacing the 2 
lets the Omni can turn on/off all the features of the Aqualink (thus 
controlling the pool) though any of the interfaces.    I let the 
Aqualink worry about freeze protection and do the normal pool schedules 
through that controller,  since that is very clean.  You can set flags 
though programming, based on input from the Aqualink to the Omni,  that 
can allow the Omni to show pool status using one of the HA Web programs 
or the Phone interface.

The only problem with doing this is that you have to use the message 
array of the Omni to hold all the messages that can be sent/received by 
the Aqualink.   That array may be undersized  to hold *all* the messages 
that can be sent/received by the Aqualink  if you use audio messaging 
and/or interface to other controllers for controlling other things such 
as sending IR messaging that also require message strings.

Hope this helps.
