When using openhab it should open up more possible units as you don’t need co2 in the weather station as you could use a zwave co2 sensor and a more basic weather station for the rest.
Not Many stations can connect direct to openhab and be cloudless, this one can do that plus still upload to weather underground which there is also a binding for.
Many brands sell that weather station Re badged so just do a search in your local country and if it looks the same it will be. They make versions with better screens but you will need that box which can be purchased separately to get the connection to openhab without a cloud.
Just a heads up that weather underground are making big changes to their api in the next month and this will probably break the binding and require changes to be made, they have not released full plans and details yet. The binding for the ip observer unit should keep working through the WU changes and it is found here…
