Nest Hello Troubleshooting: Low Power / Nest Hello Transformer Issues
If you installed your Nest Hello smart doorbell and are getting yellow light ring around your Nest Hello is means that you have low power at your doorbell transformer and will need to upgrade it to a higher powered transformer. The Nest Hello Voltage requirements are 16V - 24V AC so you will need a Nest Hello compatible transformer. We have a separate in depth post that covers everything you need ton know about Nest Hello transformer installations. But here’s the short summary of what you need to know about the Nest Hello Transformer and how you can quickly fix the issue. If you know where your doorbell transformer is you can swap out your existing transformer for a 16V -30VA hardwired transformer like this one on Amazon. We have tested this transformer and thousands of installations have confirmed that it works with the Nest Hello.
It’s important to get at transformer that is 16V - 30VA rated. We have found that the typical 16V - 10VA transformers that seem similar that you can find at most local hardware stores don’t alway provide enough power which is why we recommend the 16V - 30VA rated doorbell transformers which provide more power to the Nest Hello Doorbell.
If you have a longer run of wiring 60-80+ FT you might need a higher powered 24V transformer here to power your Nest Hello. This is covered in more detail in our Nest Hello Transformer specific post but if you know you need a higher powered 24V Nest Hello Transformer we recommend this multi-voltage transformer.
If you want to check your transformer voltage before getting started with your Nest Hello installation you can do so by just unscrewing your existing doorbell and putting a multi meter across the terminals on the backside of the the doorbell. We have found this multi meter to be easy to use and reliable.
If you don’t have easy access to your existing doorbell transformer, or you don’t feel comfortable rewiring high voltage and installing a built in hardwired transformer, you can use a plug in transformer that plugs into to a wall socket and then connects to your doorbell wiring. You would need to either cut or remove your existing doorbell wiring from the existing transformer but this offers a simple way to provide power to your Nest Hello without needing to touch high voltage wiring. This post covers how to install a plug in transformer with the Nest Hello.
