Writing Value for EMS_EP_RESERVE #68
Description
I tried to write the value for Emergency-Power-Reserve via RSCP to my E3DC
Reading the value works fine.
But if I try to write, I always get NULL back and the value don't change.
Can anybody help me please? Thanks in advance.
I have found that this value is % of the installed batterie capacity, and it is given als float32 eg 25.00 etc.
def set_epr(self, ep_reserve=None, keepAlive=False):
res = self.sendRequest(
(
"EMS_REQ_EP_RESERVE",
"Container",
[
("EMS_EP_RESERVE", "Float32", ep_reserve),
],
),
keepAlive=keepAlive,
)

After several attempts I did it like that and it worked, setting EP Reserve to 1650 Wh:
Idea borrowed from here: https://github.com/nischram/E3dcGui/blob/1ed3dc163287f7227b303e22d4ff20c650143ad0/Rscp/RscpSet.cpp#L105

Only thing is that for some reason the new value does not update on the touch screen UI, but it actually works.

@Selaron
I can confirm this.
The display stays with the old value.
Also reading the set value was a bit difficult.
You only get a % value, but this % is calculated by installed capacity and state of health of the batteries.
For me it work perfectly now.

Using this you can get the Wh reserve setting:
The
[2][2][2]extracts the value out of the tuple.
