Coordinate multiple nests for demand pricing

This question was asked earlier this year (by Chad) but the response didn't answer the original posters question:

 

I have 2 well functioning nests in a 2-story 3k sqft home in Glendale, AZ

Power company (APS) uses demand pricing - essentially using the 1 hour each month with highest electricity demand with a multiplier to figure monthly power bill.  

Given the demand pricing structure, I'd love to find a way for my two heatpumps to alternate operating times (so they aren't running at the same time and spiking demand).  Is there a way for nests to DO this?? 

Thanks for any input 

I have the same question. Can the devices work in together to ensure they are not all on at the same time if that is the desired outcome to minimize demand pricing from APS.

 

Thanks

The Nest itself cannot do that. Having said this, you can installed a special relay that links both heat pump systems together in such a way that only one of the two systems can be operational at a time.  You can also install an override switch to allow both to be able to operate at the same time if desired.

Thats what it looks like. I might try something with a schedule that they could be in use every 15 min with low/highs extreme that they would not need to be on at the same time.
