By the way (yes ... I'm requoting an old post) ... Did you also face issues with BLE and syssi Software ?I´m working on my personal version to connect 3 JKs via mqtt to the CAN ESP and have just published the project here:
The CAN Controller subscribes to the JK-Topics, calculates min/max/avg/sum of the relevant data and then acts like an virtual BMS for the inverter. My JK-ESPs also run syssi´s repo and connect via BLE![]()
GitHub - octane321/esphome-Mqtt2Can-iobroker: Adaption to use mqtt to control your Inverter via CAN
Adaption to use mqtt to control your Inverter via CAN - octane321/esphome-Mqtt2Can-iobrokergithub.com
Its still work in progress, but it runs fine on my deye productive inverter
Feel free to have a look and maybe it helps you out until we have a standalone multi BMS Version which works without a mqtt broker.
I know they recently released a major update that requires some re-configuration. I'm still on the old version, but my ESP32 connected via BLE report periodically "Offline" (approx 6h duration, happens every 2-3 weeks). Did you also encounter this issue ?
I initially greatly improved the reliability by essentially gluing the ESP32 on top of a Polycarbonate plate on top of the BMS (~ 30cm), so it should have excellent WiFi and BLE connectivity. Yet it drops off from time to time.
Initially I thought it was the BMS that went offline and all protections got disabled all of a sudden
