Show on TV Chromecast / Google TV, TV browser or VLC - not encrypted
Turns this picture into a small video a TV can play, about 20 s behind: press Cast for a Chromecast or Google TV on this Wi-Fi (this loads Google's cast library, only then), or open the link in a TV browser or a player such as VLC.
Not encrypted, unlike Share live: clearevo.com holds the last few seconds of the picture so the TV can fetch it, and anyone with the link can watch. Stop it when you are done.
This browser cannot play the stream itself, so there is no preview here (Chrome on Android has one). Cast, the link or the QR code still work.
TV browser or a player such as VLC: open this link

Press Connect and pick your JK (JiKong) BMS in the Bluetooth chooser - readings stay on your device.
Needs Chrome or Edge with Bluetooth (Android or desktop). The chooser lists every nearby Bluetooth device - pick the BMS (JK units often advertise a plain name).
No BMS nearby? See it live: the author's LFP banks
Keep Bluetooth on: with it off, a reconnect on this Chrome version can close the tab.
Cell voltages bar height exaggerates the spread: scale runs from the lowest cell - 50 mV to the highest + 50 mV

Debug logs
More same frame as the meters, not covered by the cell-sum check; offsets verified against captured frames from 24-cell, 32-cell and JK-PB firmware (see how to use)
BMS settings as configured in the BMS (read-only here)
Notes
Time to empty counts down to your inverter's low-battery cut-off at % of capacity (default 10 %, set your inverter's value). Straight-line from the smoothed current; charging slows near full, so time to full is optimistic.
A JK BMS accepts one app at a time - to use the JK app again, press Disconnect here first.
Chrome keeps the screen on while media plays; some phones let go of the normal screen lock after hours (seen on an old Sony). The video is silent (1 % volume), but Android may lower other apps' sound while it plays.
Alerts Chrome notifications when the battery needs you
Debug raw frames - check these if the numbers look wrong
Upload sends this log to clearevo.com only after you confirm the warning: browser and device details, raw BMS frames and readings, the BMS name and serial. Never the share-link key. Kept 90 days, read by the site owner to fix what you report.
