Esphome testing and Battery Capacity Issues

niky8907

I'm testing the board with Esphome, I had the same problem before, when i choose the battery capacity, I have this situation

21:53:07

[component:237]

Component powerfeather_mainboard took a long time for an operation (56 ms).

21:53:07

[component:238]
Also I have this warning on webpage

Components should block for at most 30 ms.

niky8907 Hi, thanks for creating the post here. I just have a question, when you say " i choose the battery capacity" what do you mean? Do you mean the config parameter in the yaml:

powerfeather_mainboard:
  id: "my_powerfeather"
  battery_capacity: 1000           # <---------------- this one?
  battery_type: "Generic_3V7" 
  update_interval: 5s

I ask because the picture you posted is not of this - instead, the picture is of the dashboard controls. Do you mean perhaps one of these dashboard controls?

I posted the behavior of the dashboard control when I tried to modify the YAML.
I observed the same behavior while testing the board with the PowerFeather-Demo code.
I have four Sanyo UR18650ZM2 batteries in parallel, so I tried changing the configuration as follows:

battery_capacity: 9880

Is this incorrect?

niky8907 The max is actually 6000. In case of parallel, the capacity of a single cell must be used. This limitation is inherited from the LC709204F fuel guage:

parallel-capacity

I realized I didn't mention this in the ESPHome config documentation, will fix.

By the way @niky8907, please do mark this as solved if the previous answer works for you.

Yes, but I’m not sure if this behavior is normal.

I didn't encounter this when I was testing the component, can you share your entire config yaml (minus the "secrets" of course, like wifi password etc.)?
