Help Porting ST Carrier Infinity/Bryant Thermostat Driver and APP

Is there anyone that would be willing to help port this App and Driver?

I'm down to 3 lines of code that i need converted.

javax.crypto.Mac mac = javax.crypto.Mac.getInstance("HmacSHA1")
mac.init(new javax.crypto.spec.SecretKeySpec(oauth_key.getBytes(), "HmacSHA1"))
return mac.doFinal(oauth_base.getBytes()).encodeAsBase64()

I added:
import javax.crypto.Mac
import javax.crypto.spec.SecretKeySpec

and Changed:
javax.crypto.Mac mac = javax.crypto.Mac.getInstance("HmacSHA1")
mac = javax.crypto.Mac.getInstance("HmacSHA1")

Now Getting Expression [MethodCallExpression] is not allowed: javax.crypto.Mac.getInstance(HmacSHA1)

@damon.dinsmore - we're you ever able to get this ported?

Unfortunatly no luck. There is a need to get Hubitat to do this as a true integration as a key is needed from Carrier

@damon.dinsmore I'd like to give this a shot. Would you mind sharing where you got to and what you have from a code perspective please?

Hi all, did anyone get to a solution on this?

I am going to be replacing my HVAC and this topic is of interest to me.

I was able to get some documentation on the topic, if that helps.....

And I've attached a document from the HVAC company with more instructions....

Did you ever come up with a solution here? I hate the hacky one I have.

Has anyone tried requesting a key from Carrier? There are instructions on their API documentation page.
