bt-sensors-plugin-sk This plugin cand detect a Daly BMS?

The plugin will detect any device that advertises but not be able to parse any relevant values without some investigation. Every bluetooth device has its protocol for broadcasting data. I'd have to know what that is. Then develop and test a Daly BMS connection class.
There is a HomeAssistant / MQTT alternative called batmon-ha that's interesting https://forum.esk8.news/t/homeassistant-bluetooth-bms-monitoring-server-guide-esp32/78833 Can't vouch for its accuracy though. If batmon-ha works with the Daly then I (or some other less busy programmer) can create a nodejs connection class for it.
In any case, I'll put Daly BMS on the list of bluetooth devices to be supported. Writing a connection class will take a time and some back and forth with you or another Daly user (as I don't have the device on hand).
There is also this European Bluetooth BMS, 123SmartBMS (https://123electric.eu) that I am considering for my conversion to LiFePO4 next year. I guess it is not popular enough to warrant efforts to have it covered in a SK plugin but there is some information here: https://github.com/123electric/smartbms-thingspeak
@Sailabout if you can find the Bluetooth protocols, I can put the 123smartbms in the queue of sensors to do. NB: The link refers to a project that uses the device's serial protocol.
Here explain how to connect daly bms to node red. I can Try it on my daly bms if you include daly bms into the plugin.

My plan as of today is to develop support for Renogy, Juntek and then Daly BMS systems and smart batteries (in that order as that was the order in which they were requested). I haven't yet recruited a developer on this forum who can help me so I ask for your patience. Eventually, I'll need you to test which will likely involve some going back and forth.
