misc/soliscloud-inverter-control#9: Provide ability to change charge rate

Issue Information

Issue Type: issue
Status: closed
Reported By: btasker
Assigned To: btasker

Milestone: PoC

Description

The API doesn't currently expose the ability to change the charge or discharge rate.

I'd like to be able to change these on demand.

There are two ways that we could go about this:

  • Change start* endpoints to accept a rate in the post body
  • Add a new endpoint which simply changes the rates

The second way would allow independent changes, but would usually mean 2 API calls (which by extension means Soliscloud has to set registers twice).

I think the answer is probably to implement both

feat: allow custom charge rates to be set (misc/soliscloud-inverter-control#9)

This allows new charge and discharge rates to be provided when triggering an immediate start or stop

+25 -10 (35 lines changed)

The following functions now accept an optional argument rates

  • immediateStart()
  • immediateStop()
  • startCharge()
  • stopCharge()
  • startDischarge()
  • stopDischarge()

When supplied, rates is a dict which contains one or both of charge_current and discharge_current

The stop* functions support it so that current settings can be changed back if they were boosted when calling immedateStart()

feat: start/stop end points can accept charge rates (misc/soliscloud-inverter-control#9)

The start/stop endpoints can now accept charge and discharge rates.

This ticket can't be closed yet though, we also need to give the control server and API endpoint to only change the rate (so that rates can be put back without interrupting charging).

feat: new endpoint to set current without changing timings (misc/soliscloud-inverter-control#9)

+59 -0 (59 lines changed)

The commit above adds an API endpoint to the control server: /api/v1/setCurrent

This accepts a JSON payload

curl -H "Content-type: application/json" \
-d '{"charge_current" : 30, "discharge_current": 55}' \
http://127.0.0.1:8081/api/v1/setCurrent

In order to support this, the python library also has a new method

soliscloud.setCurrents(rates)

rates is a dict:

{
  "charge_current": 30,
  "discharge_current": 55
}

The function will read configuration from the inverter, overlay the provided currents and post back.
