ioBroker adapter for AdvanSol DCON-WIFI / MRO/MR optimizers connected through a TCP-to-RS485 bridge, for example a Waveshare ETH-to-RS485 adapter.
Product and manufacturer information is available on the official AdvanSol Power website.
The adapter is based on the original ioBroker JavaScript script Advinsol Optimierer2 and moves the logic into a dedicated ioBroker adapter namespace.
Features
- Connects to a TCP RS485 bridge.
- Reads the controller serial number.
- Discovers connected optimizer modules automatically.
- Polls module values cyclically.
- Switches each optimizer MOS through
module_X.switch. - Skips polling during a configurable night window.
- Exposes connection state and night mode states.
Typical Setup
- ioBroker runs in the local network.
- A TCP-RS485 bridge is reachable via LAN or Wi-Fi.
- The RS485 side of the bridge is connected to the AdvanSol controller.
- The controller communicates with the optimizer modules.
Recommended bridge configuration:
- Mode: TCP server
- Port: same as configured in the adapter, default
502 - Serial settings: matching the AdvanSol controller and RS485 bus
- RS485 A/B connected correctly
- Only one active master on the RS485 bus
Adapter Settings
| Setting | Meaning | Default |
|---|---|---|
Host | IP address or host name of the TCP-RS485 bridge | empty |
TCP port | TCP port of the bridge | 502 |
Polling interval | Time between polling cycles in milliseconds | 10000 |
Request timeout | Maximum wait time for a response | 5000 |
Switch retries | Number of repeated MOS switch commands | 3 |
Switch retry delay | Delay between switch attempts | 4100 |
Night mode starts | Hour where polling is skipped | 22 |
Night mode ends | Hour where polling resumes | 5 |
The night window avoids unnecessary errors when optimizers do not respond at night or without PV-side voltage.
States
General states:
| State | Meaning |
|---|---|
info.connection | Connection to the TCP-RS485 bridge |
connection | Additional connection state |
controller.sn | Controller serial number |
module_count | Number of discovered optimizers |
last_poll | Time of the last successful poll cycle |
night_mode | Adapter detected night mode |
Each optimizer gets a channel named module_1, module_2, module_3 and so on.
| State | Meaning | Unit |
|---|---|---|
module_X.sn | Optimizer serial number | |
module_X.switch | MOS on/off, writable | |
module_X.mos | MOS status, 0 off and 1 on | |
module_X.software | Software version | |
module_X.hardware | Hardware version | |
module_X.output_voltage | Output voltage | V |
module_X.output_current | Output current | A |
module_X.input_voltage | Input voltage | V |
module_X.input_current | Input current | A |
module_X.power | Power | W |
module_X.energy | Total energy | kWh |
module_X.temperature | Temperature | °C |
module_X.raw | Raw response as hex string | |
module_X.last_update | Last module update |
Switching Optimizers
The state module_X.switch is writable. Setting it to true sends the MOS-on command for the module serial number. Setting it to false sends the MOS-off command.
The adapter repeats the command according to Switch retries and waits Switch retry delay between attempts. This is intentional because TCP-RS485 converters and optimizer modules may not acknowledge every command immediately.
Troubleshooting
- No connection: check IP address, port and TCP server mode of the bridge.
TCP connect timeout: bridge is not reachable or the port is wrong.- No modules discovered: check RS485 A/B, controller power and PV-side supply.
- No daytime responses: check RS485 parameters and wiring.
- No nighttime responses: usually normal if optimizers sleep without PV voltage. Adjust the night window.
- Switching does not work: serial number must be known, module must respond, increase
Switch retriesif needed. - Multiple systems on the bus: make sure there is not more than one active master sending frames.
