I have a couple of job coming up where I will be integrating with Nest for the first time. ?From what I see in the module, you are only able to access one thermostat at a time from the Crestron system as a whole. ?I'm assuming it would be a bad idea to put more than one instance of the module in a system, correct? ?I really don't like the possibility of two people on two different interfaces not being able to each adjust their own remote. ?That probably will very rarely happen, but I can see a few other reasons to have direct access to each thermostat at all times.

I've done quite a bit with the Nest module recently - added in discrete Home/Away inputs and feedback into the Simpl+ Nest Processor and also tidied the Simpl wrapper to account for UK Nests, including a Call Heat output (I'm in the UK).

From what I can see, you should be able to have multiple instances of the Simpl Module and you would simply add a startup pulse (use a delay of 20s on processor startup) to trigger the appropriate Thermostat Select input. Belt and braces, I'd also send the select pulse each time the user accesses their particular?Nest page, but from my experience, once a stat is selected, I've never seen it deselect.

I'd love to, but since?the basis?of the code is from the Crestron simpl+ module, I don't think forum rules will allow it - if anyone can confirm this is not the case, then I will gladly post the module.

Also, bear in mind that I've stripped out all the code related to cooling since the UK Nest only supports heating, although using a text comparison tool (Beyond Compare, for example) you can easily see what I've stripped out and what I've added.

The heatcall function I've added is only based on the difference between target and ambient temperature because unfortunately the Crestron Simpl# module is missing?the API object called "hvac_state" and Crestron?unfortunately won't release the source code for this (I have asked :)

I'm hoping they will release an updated simpl# module in due course with this object added.
