replacing Era 100s with Era 300s
Hi everyone. Please excuse me I am not very technically minded just need a little help. I am replacing my era 100 (2 of them) with era 300. Do I just need to add them to my existing system & then follow the app instructions? Many thanks for your help & any info you thinkย might help would be great. The era 100 are going in another room by the way.๐
