I have just set up an account with Netatmo to take a quick look at this and I managed to get it working by setting the Authentication type to Body, Can you give this a go and let me know if it works for you.
Hi @Jon,
Thanks for your answer, Super happy you managed to get it working! I have been spending at least 2 hours… But I don’t undersatand enough authentication to manage to do it by myself here… Sorry!
