Gerber Prime 6000

Reverse-engineered notes and code samples for controlling the Gerber Prime 6000-series smart-home controller (relay / dimmer / roller-shutter DIN-rail box) locally over HTTP, with no vendor cloud.

If you own one of these and want it in Home Assistant / Node-RED / a script instead of the "Home Mate 2" phone app, this is for you. Everything here was worked out by observing the device's own web UI — there is no official public API doc.

⚠️ Unofficial and community-maintained. Not affiliated with or endorsed by Gerber. Use at your own risk — the switch command actuates real relays/shutters.

What device is this?

• Vendor: Gerber Prime (gerber-home.net / gerberprime.com), phone app "Home Mate 2".
• DIN-rail controller, 8 outputs via hot-plug dongles (relay / dimmer / curtain-shutter), 8 inputs. Marketed as e.g. GPS-6000 ("Shutter module 5A×4, Relay up to 5A×8"), GPB-6000 (FCC ID 2AQO4GPB-6000).
• The Wi-Fi control module identifies itself as PSC05 (a sibling PSC03 exists). Its config Access Point is named PSC05-<wifi-mac>.
• Embedded Linux, Apache/2.4.12, web UI code version 2.0.21 (2018). Internal platform string seen in API responses: PAN27.

If your unit's setup Wi-Fi is called PSC05-xx:xx:xx:xx:xx:xx, this repo applies to you.

Default credentials (vendor defaults, from the FCC manual)

What	Value
Web UI / API login	admin / 888888 (HTTP Basic)
Config Wi-Fi (SoftAP) WPA key	12345678
SoftAP gateway IP	10.10.10.254

(Change these if you can. They are the shipped defaults, published in the FCC manual.)

Two local interfaces

The web UI is backed by two CGI endpoints (both HTTP Basic auth):

• /sdk.cgi — device control & status (turn relays on/off, read all channels, Z-Wave include/exclude, config params).
• /network.cgi — network / Wi-Fi config (AP↔STA mode, SSID, scan, reboot).

Full reference: docs/API.md.

Quick start

pip install requests   # optional; the sample also works with urllib
python examples/gerber_client.py --host 10.10.10.254 get-devices
# turn relay channel 3 on / off (uid comes from get-devices):
python examples/gerber_client.py --host 10.10.10.254 switch --uid 257 --chid 3 --on
python examples/gerber_client.py --host 10.10.10.254 switch --uid 257 --chid 3 --off

See examples/gerber_client.py (Python client), examples/curl.md (raw curl), and examples/home_assistant.md (HA rest_command sketch).

Home Assistant users: there is now a ready-made MQTT bridge with HA discovery (switches + positional shutter covers, availability, no HA YAML needed): gerber-prime-6000-mqtt-bridge.

Hard-won gotchas

• Request encoding for /sdk.cgi: the UI sends POST with a single form field json=<encodeURIComponent(encodeURI(<json>))>, i.e. the JSON is double-encoded. The sample client reproduces this. Responses are URI-encoded JSON — decode before parsing. respcode: 100 = OK.
• Switching the unit to Wi-Fi station (STA) mode via the API does NOT work reliably. Setting setstassid / setstapwd / setwifimode=STA / wificommit over /network.cgi repeatedly failed to complete a join (across WPA2, WPA2/3, and even an open SSID) — the raw calls don't seem to set the SSID's security type. What worked: do the STA switch from the device's own web UI, picking the network from its scanned list, then power-cycle the unit. After that it joins and is reboot-stable. If you've cracked the pure-API STA path, please open a PR.
• Old Wi-Fi stack. In STA mode the (2018-era) client may fail to associate to APs that require 802.11w/PMF or use fast-roaming/band-steering. If it won't join, try a 2.4 GHz, WPA2-PSK, PMF-disabled SSID (or briefly an open one to prove it out).
• Recovery: if Wi-Fi/config gets wedged, power-cycle the unit (mains off/on) — this is non-destructive. It falls back to its config AP. Do NOT hold the Reset button ~5 s — that is a factory reset and wipes your scenes / channel names / bindings.
• Modbus: the RJ11 port is RS485/Modbus. The master/slave toggle and Modbus address are in the web UI (Settings → PAN27 Information → Modbus Mode). Default is master; set slave if you want to poll it from an external Modbus master (e.g. an RS485→TCP gateway).

Data model (from get_all_device)

Each device has channels; each channel has a ctrltype/functype:

ctrltype	Meaning	Control
23	On/off relay ("Wall Switch")	switch cmd, val 0=off / 255=on
26	Roller shutter / curtain	switch cmd — up/down/stop val mapping not yet confirmed (help wanted)

Shutter travel time (seconds/channel) and Modbus settings appear in a pan27_info block.

Status / help wanted

• ✅ Read all devices/channels; ✅ relay on/off; ✅ Wi-Fi mode/scan/config; ✅ Modbus mode toggle.
• ❓ Roller-shutter open/close/stop command — not yet nailed down. PRs welcome.
• ❓ Pure-API STA-mode join (UI flow needed today).
• ❓ Dimmer channel control (val as brightness?).

Contributions from other Gerber Prime / PSC05 owners very welcome.
