Parameters from Delta 2 Max

[Neewieedo]

Hi,
I have two questions/ideas about the parameters of the Delta 2 Max.

1. Do I understand correctly that you can set the AC charging speed using the entity number.delta_2_max_ac_charging_power and does that work for you? I always get 2400W displayed in the app.

2. Would it be possible to query and display the volt and ampere values ​​of the two MPPT trackers?

As I understand the parameter list, it should be available in the interface:

• mppt.inAmp | int | PV1 input current (mA)
• mppt.inVol | int | PV1 input voltage (mV)
• mppt.pv2InAmp | int | PV2 input current: The current voltage is amplified 100 times.
• mppt.pv2InVol | int | PV2 input voltage: The actual voltage is amplified 10 times.
• source: https://developer-eu.ecoflow.com/us/document/delta2max

And one more little thing, that would also be interesting :-)

• bms_emsStatus.fanLevel | int | Fan level

I hope someone can take care of this and find a solution.

Have you the switch on the backside of the D2M in the right position?

Thank you for the tip! The switch was set to fast.
I didn't even know that this switch existed :-)

I set the switch to slow and now I can set the AC charging value

Is there an easy way to query the values ​​via the http interface for testing purposes?

Hi,
I'm posting here since my questions are about Delta 2 Max parameters. Let me know if I should move this elsewhere.
I'm a beginner with Home Assistant, and just integrated my Delta 2 Max. Thank you very much for making this possible.

So, I'm trying to set up a simple automation where the trigger is the battery level.

1st question : what's the difference between entities "battery_level" and "main_battery_level" ?
I can see the latter has more state attributes, but I'm not sure which one I should use for the automation.

2nd question : why is HA not readily reading values from these entities? It just reads "unknown". How can I fix this?

With this I'll be on my way to my first automation ever!

Are the solar inputs of the battery always switched off when the maximum charge level is reached?
Can't the generated solar power simply be passed on 1:1 to the PowerStream?

@tolwi Is it possible to add these parameters to the Delta 2 (Max)?

• mppt.inAmp | int | PV1 input current (mA)
• mppt.inVol | int | PV1 input voltage (mV)
• mppt.pv2InAmp | int | PV2 input current: The current voltage is amplified 100 times.
• mppt.pv2InVol | int | PV2 input voltage: The actual voltage is amplified 10 times.
