Signify / Philips Hue
By implementing Philips Hue API into my app, it now sends personal information to them (ip-address), Hue bridge data, session time, color of lights, etc, and an ip-address is regarded as personal information under GDPR therefore I need to have the end user consent for this within my app.
Philips Hue has it's own privacy policy but they also refer to Signify and I regard their privacy policies as difficult to comprehend, and I would like you to add their privacy policies in your service.
