Dear Homey Developer Support,
I am developing a custom driver for the RCS TBZ48 thermostat.
I will be leaving the country on the 9th of this month for more than six months. Since debugging requires physical access to the device within the same LAN, I urgently need to resolve the remaining platform-related issues before departure.
Repository:
> **[GitHub - qiuzux/homey-rcs-tbz48: Homey Pro 2023 driver for RCS TBZ48 Z-Wave...](https://github.com/qiuzux/homey-rcs-tbz48)**

> Homey Pro 2023 driver for RCS TBZ48 Z-Wave thermostat
I am encountering two platform-level inconsistencies.
## 1️⃣ Secure State Fluctuation
Observed:
- Secure (S0) was successfully negotiated in earlier inclusion
- Developer Tools now display secure state as: Secure: x
- Facts:
- Can Homey downgrade a node from secure to non-secure post-interview?
- Does a failed nonce exchange result in non-secure classification?
- Is there any caching behavior affecting secure display?
-
## 2️⃣ Battery Capability Status
Facts:
- BATTERY\_REPORT received
- Battery percentage logged correctly
- measure\_battery capability implemented
Issue:
- UI occasionally displays battery state as unknown
Questions:
1. Does Homey require explicit WAKE\_UP handling for battery capability stability?
2. Is measure\_battery dependent on polling configuration?
3. Does Homey mark battery as unknown if no report is received within a specific timeout?
4. Is registerCapabilityListener required for battery devices?
Condensed Log Extract:
Node Interview Complete
COMMAND\_CLASS\_BATTERY supported
COMMAND\_CLASS\_SECURITY supported
Battery Report received: 87%
Secure: false
Wake Up Notification received
I would appreciate clarification on:
- Secure state evaluation logic
- Battery capability state handling for sleeping devices
Given the time constraint before my departure, your prompt assistance would be greatly appreciated.

Why does AI add an empty line between each and every mf sentence? (I know, old folks annoyances here 🤣 ).
On topic: does VPN ring a bell?
You can safely connect to your home LAN from remote places.

Thanks for the heartwarming help.
Have just done as this.

Empty line is caused by my copying method.
Good ideal, I will try VPN.

Yes, I would also recommend a VPN. Do not open up ports to your Homey via port forwarding, that’s not a safe way to connect.
If you have a desktop PC, you can also keep it powered on and then install [RustDesk](https://rustdesk.com/) to remotely access it. This is what I use to remotely connect to my PC for developing my apps while I’m away from home.
