You want to use the play store version. I'm running 3.12.4 from the Play 
store and when connected to a Leaf, I see the AC button.

Not all cars support lock and unlock or valet mode. We have some code 
that works for lock/unlock on the Leaf but it's not yet finished. There 
are no plans to support valet mode.

You don't need this for OVMS v3.

We still support climate control with homelink 1 & 2 for old apps. This 
at least lets use separate your climate control button problem questions 
about how the AC works.

Which model year Leaf do you have? Older than 2013 may require extra 
hardware to enable climate control when the car is asleep. 2013 through 
2015 use a different remote climate control to that of 2016 & 2017. You 
have to set the module year configuration option to tell the OVMS which 
car you have. 2018 Leafs are not yet supported.

We made a change to how the climate control is switched off recently and 
this is probably in the latest firmware (which you don't have on your 
OVMS). We don't have a way way to configure the remote climate control 
-- the OVMS simply sends the enable command to the car and the car does 
it's thing.
