Hi @dailo,

Thank you for posting in the community. I’m sorry to hear that you're getting an "E44" error code on your Nest Thermostat, even after installing a Nest Power Connector. I understand how frustrating this trouble must be. I appreciate you sharing the relevant information about you having the same issue before in your old house, but no worries, I'm happy to assist.

To gather the necessary information, please answer the following questions:

• What type of Nest Thermostat do you have? Please see: How to tell which Nest thermostat you have.
• What type of HVAC system do you have?
• Can you confirm the wires are fully inserted into their terminals?

I'll be waiting for your reply.

Best regards,

Derick.

no need for help.  I chatted with a live agent and that'd helped quicker than you.  It was my base that was garbage and a replacement is on its way.  by the way it was an E thermostat that wasn't working...
