Mesh Products in deep sleep wake on USB/VIN power state change

Could you try a large capacitor across the VIN as a buffer from the solar panel controller - and could you post the solar panel you are using ? Obviously a night / day transition will wake device but it may stop the “cloud” based wake ups?

It covers a lot of ground and the last post provides power savings of the varies modes
