Electrodacus SBMS adapter for ioBroker

Simple adapter to make data from Electrodacus SBMS available as states from MQTT, the rawData html page or the serial port.

Units and structure was a little customized from original data stream. If full message option is enabled, original data is additionally pushed to sbms.x.mqtt/html/serial folders.

In any of the 3 methods with WIFI enabled, I found that even with 1s Update Intervals, often only every 2s new data is provided as can be seen on the sbms.time.second field, so thats the maximum to be expected. To get consistent 1s Updates use Serial Port and the on SBMS set USART Data Log Option to 1. This way, counters and balancing info is not accesible.

Tested on SBMS0 only.

Serial Port / USB with Wifi Extension Board

1. In SBMS check Baudrate (fixed to 921600 with Wifi activated)
2. Connect host to SBMS USB (or use USB to Serial Adapter and connect diretly if you dont have Wifi Extension Board)
3. On host identify serial port with ls /dev/serial/by-id
4. Configure in the adapter admin page accordingly
5. Adjust Updating intervall (1s: full stream is processed)

Notes:

• SBMS manual says the baudrate 921.6k may not be reliable.
• If Serial Port is configured in Adapter admin, MQTT and HTML is deactived.

MQTT

1. Setup MQTT Broker and connect iobroker
2. Connect SBMS to wifi and MQTT broker
3. Identify ioBroker state that receives the SBMS JSON (default root/sbms)
4. In the SBMS adapter configuration name topic in the iobroker format with dots
5. Adjust Updating intervall (1s: every update of the topic state is processed)

rawData Html Page

rawData html page has additional infos (eg. counters and balancing)

1. Connect SBMS to wifi
2. Identify IP and set static (wifi router)
3. In the SBMS adapter name IP adress
4. Adjust Updateinterval

If MQTT and HTML options are enabled, basic info is updated from MQTT stream whereas battery parameters and counters from the rawPage. balancing is not put in the general datastructure.
