Backup Mode

[pprWLC]

First of all: Thank you for your yaml files!
Is it possible to add a script to enable and disable the backup function of the battery?

Don't know what you mean by script. You can call the select.select_option action on the select.esphome_web_745c70_marstek_backup_function entity from any script or automation in home assistant. Op di 25 feb 2025, 20:03 schreef pprWLC ***@***.***>:

I use the marstek_venus_battery_control.yaml because my battery is directly connected via usb-ModBus-Adapter.

There is no Input select for the Backup function in marstek_venus_battery_control.yaml and I thought you first have to enable writing before enabling the backup function.

I think enable writing is only needed for the charging en discharging commands/registers, check the modbus register doc. (pdf). If you combine the existing samples in the yaml file the backup function definition in the esp file it shouldn't be too hard to add it (or have chatgpt do it for you ;-) ). I have my esp connected to the battery so can't test changes to the ha modbus stuff. Full free to make a PR if it is added. Op wo 26 feb 2025 om 06:08 schreef pprWLC ***@***.***>:
