Honeywell Evohome thermostat: work started, need advice

Development

@PItax,

Yes @namadori’s code does stop working after an hour. It’s because it uses evohome-client2 (which uses v2 of the honeywell API), after the OAuth token runs out. There is a way to extend token life - but it seems (to my noob eyes) that this is not exposed within the evohome-client2 code.

Anyway, I have added the following work-around to @namadori’s code (my update code is different to @namadori’s , for val in self.client.temp...):

def update(self):
    try:
 ...
    except TypeError:
        _LOGGER.error("Update failed: TypeError (has token timed out?)")
        self.client.access_token = None
        self.client._login()
        return

I don’t think it is very pretty, but it works! My log file looks like this (FYI, HA was started at 18:07):

Notice an ERROR every hour, rather than every 5 mins after the first hour. Other than that, it behaves as expected.
