Seeking Advice on Z-Wave Integration Issues and SFTP Connectivity

Hello everyone, I’m reaching out today with a couple of issues I’ve been facing with my smart home setup. First off, I’m really enjoying the journey of integrating various devices, but there are a couple of hurdles I’m hoping the community can help me overcome.

Z-Wave Integration Puzzle
I recently set up a new Home Assistant environment and decided to go all-in with Z-Wave for my sensors. Everything seemed to be working smoothly in the Z-Wave JS UI, but when I tried to connect it to Home Assistant, I ran into this error: Failed to connect: Cannot connect to host core-zwave-js:3000 ssl:default [Connect call failed ('172.30.33.3', 3000)]. I’ve checked the network settings, restarted the services, and even reinstalled the integration, but nothing seems to resolve the issue. Has anyone encountered this before or has any troubleshooting steps to share?

SFTP Connectivity Woes
On another front, I’ve been using SFTP with my CCU2 for a while now, and it was working like a charm. However, after a few firmware updates, I noticed that SFTP stopped working entirely. I can still log in via SSH without any issues, but SFTP throws this error: Network error: Software caused connection abort. I’ve tried disabling and重新配置 SSH, resetting the CCU2, and even checking the firewall settings, but no luck so far. If anyone has any insights or solutions, I’d be eternally grateful!

A Word of Thanks
I want to take a moment to appreciate the incredible support and resources available in this community. It’s amazing how much progress I’ve made with the help of forums like this. If anyone has any tips or tricks for these specific issues, or even general advice on maintaining a stable smart home setup, I’m all ears!

Fingers crossed for some helpful insights. Thanks in advance for your time and expertise!
