I have been following the instruction below to prepare for Nest → HA integration, paid the $5 by following the instruction, but at the last step Events: I enabled it and provided a topic ID. There is a window pops up stated:
———————————————————————————-
Device Access could not publish into the PubSub topic
Device Access service cannot publish messages into the specified PubSub topic. Verify that [email protected] has the PubSub Publisher role in the PubSub topic. Make sure you have followed the prerequisites in the documentation (link)
———————————————————————————-
I am stuck and how did you create Device Access Project ID?
Instruction that I followed to integrate Nest to HA:
Not sure if it’s related (or helpful to you but my Google Nest thermostat integration stopped working as of this morning. I had it up and running for the last week. I’m just starting with home assistant. I haven’t had time to look into the error.
Will update here if I have anything useful to add.
Update: I had to re-authorize the Google Nest Integration. I only got this option/suggestion in home assistant via a notification after I had ‘published’ my project on Google Cloud. Changing from testing to published. And after I went here to set ‘Experation’ to ‘never’. Pfffff…
I’m stuck at the same point , it’s so complicated, this is my second attempt:( no idea how to fix this , google’s help is stupidly complicated to try & fix this.
Update : hours later & still no further, seems related to a permissions being an editor of the pubsub topic as well as owner, google gives the same error “ Device Access service cannot publish messages into the specified PubSub topic. Verify that [email protected] has the PubSub publisher role in the PubSub topic. Make sure that you have followed the prerequisites in the documentation” I’ve tried to look for this info but I can’t see how to change the publisher role.
Thanks for chiming in , I am surprised that many of you have the same issue.
Missing AC control (expect to access & control nest thermostats in HA), will miss quite a portion of home automation. Hope that there is a solution for our situation and I don’t need to change the thermostat to HA compatible one.
