iBMS integration - ivob - 26.10.2026
Recenlly I bought an iBMS interface for reading data for my home battery system with a JK BMS. Can anyone help me with a basic script? The iBMS has an API which provides data bij HTML. I removed some data, but the structure is:
{
"device": "iBMS-Master",
"board_type": 1,
"charge_current": 100,
"discharge_current": 100,
"capacity_remaining": 79,
"battery_soh": 100,
"batteries": [{
"id": 0,
"total_voltage": 53.12,
"current": -0.48,
"total_runtime": 17388365
}, {
"id": 1,
"total_voltage": 53.06,
"current": 0,
"total_runtime": 27409539
}]
}

Try this. Change url and group address mapping as needed.
Code:
json = require('json')
http = require('socket.http')
url = 'http://192.168.1.1/'
res, err = http.request(url)
if not res then
log('request failed', err)
else
res, err = json.pdecode(res)
if not res then
log('failed to parse response', err)
else
grp.checkwrite('1/1/1', res.charge_current)
grp.checkwrite('1/1/2', res.discharge_current)
grp.checkwrite('1/1/3', res.capacity_remaining)
grp.checkwrite('1/1/4', res.battery_soh)
grp.checkwrite('1/2/1', res.batteries[1].total_voltage)
grp.checkwrite('1/2/2', res.batteries[1].current)
grp.checkwrite('1/3/1', res.batteries[2].total_voltage)
grp.checkwrite('1/3/2', res.batteries[2].current)
end
end
