The problem with using open_manager_with_config is that you have to make assumptions about which database binding is being used.
Off the top of my head, here are 3 alternative solutions: 1. You could cache the previous value. 2. You could fix the problem downstream by using a weewx service. 3. You could use multiple inheritance, so your driver inherits both from weewx.drivers.AbstractDevice and from weewx.engine.StdService. Getting a database manager is then easy: dbmanager = self.engine.db_binder.get_manager(self.data_binding) See the Vantage driver for an example of using multiple inheritance (although it does not access the database). But, really, you should relocate the sensor! -tk On Sun, Jul 2, 2023 at 12:50 PM [email protected] <[email protected]> wrote: > I have a customized Acurite driver where I've replaced the temperature > reading with a reading from a different sensor.
