I think I’m experiencing an API error, which I only noticed it after installing the beta. I’m not sure whether it’s being caused by Venus beta itself, the beta Node Red node, or something else.

I use the API node to patch DESS settings (e.g,. the buyPriceSchedule) via Node Red. After disabling the DESS battery balancing function, I started receiving this error from the VRM API for all patch requests:

```json
{"success":false,"error_code":"validation_error",
"errors":
{"periodicFullChargeInterval":"periodicFullChargeInterval should be null"}}

```

When fetching the DESS configuration, I see the following after disabling balancing:

```json
isPeriodicFullChargeOn: false
periodicFullChargeDuration: 2
periodicFullChargeInterval: 15
...
fullChargeDuration: 2
fullChargeInterval: 15

```

I tried directly setting the objects the API was complaining about with the following settings

```auto
{"isPeriodicFullChargeOn": false, 
"periodicFullChargeInterval": null, 
"periodicFullChargeDuration": null}

```

The VRM response initially acknowledges these settings:

```json
isPeriodicFullChargeOn: false
periodicFullChargeDuration: null
periodicFullChargeInterval: null
...
fullChargeDuration: 2
fullChargeInterval: 15

```

But if I check the same settings again via another API call, they revert to 2 and 15. So I can’t figure out how to fix this… for now I just set the interval to a large value.

EDIT: I should clarify, I’m getting this error when configuring buyPriceSchedule

I ran into this quite some time ago as well. There was some ambiguity or documentation issue about setting null versus zero versus false but I forgot what precisely, I do remember the duration/interval numbers didn’t matter as long as periodicfullcharge was switched off. It took some trial and error testing to be able to switch it on/off on demand, unless there have been undocumented API changes in between.

@UpCycleElectric Interesting… so you’re on the latest beta, have DESS balancing disabled, and the API node lets you patch other DESS settings?

My config looks the same. Initial guess: try set to false, 2, 14 instead of false, null, null

I do not need the API to patch config currently. If you give me a (harmless) json to inject I can test for you.

Back then I was testing isScheduleSocOn, scheduledSocGoal, scheduledSocTime that is a) not implemented and b) _does_ require 0, null, null respectively. You know, the infamous b\_goal\_SoC and b\_goal\_hour port from Node-RED DESS that I am catching so much heat on for requesting it for over a year already, and what we now ‘emulate’ by setting virtual forecast adjustments.😉

EDIT: found the old flow in backup.

        "modules": {
            "victron-vrm-api": "0.4.1"
        }
    }
]

```

for on:

```javascript
{
    "isPeriodicFullChargeOn": true,
    "periodicFullChargeDuration": 0,
    "periodicFullChargeInterval": 1
}

```

for off:

```javascript
{
    "isPeriodicFullChargeOn": false,
    "periodicFullChargeDuration": null,
    "periodicFullChargeInterval": null
}

```

That worked worked fine to switch DESS into and out of ‘balancing’ mode on the hour for an hour.

But it would indeed default back to

```auto
isPeriodicFullChargeOn: false
periodicFullChargeDuration: 2
periodicFullChargeInterval: 14
...
isScheduledSocOn: 0
scheduledSocGoal: null
scheduledSocTime: null
...
fullChargeDuration: 2
fullChargeInterval: 14

```

in the return object.

So if this does not work anymore, you might be on to something.

Thanks for checking. Seems there’s indeed a bug somewhere.

I guess for now I can just continue setting the interval to something like 100 days, and then when I want to balance set it to 0 days.

@dfaber just flagging for you.

This worked though (changed back battery capacity to my own):

```javascript
{
    "batteryCapacity": 87.35,
    "isPeriodicFullChargeOn": false,
    "periodicFullChargeDuration": null,
    "periodicFullChargeInterval": null
}

```

Ah good point… so alternatively, for every API request just include those 3 parameters until fixed.

Or use a large enough rolling (EV) forecast adjustment to make DESS hit 100% often enough not having to manually balance anymore. Basically invert the current ‘Sell to MinimumSoC’ bias to a ‘Buy to Full’ bias. As I would argue is the better option for DESS Trade anyway. Added bonus is you can finetune the forecast adjustment not to miss neither sell nor buy opportunities, and let DESS optimize the rest.

PS: and indeed the return object defaults back to false, 2, 14

So apparently you’d need _at least_ to pad your config change json with “periodicFullChargeInterval: null”

Check _your_ inject node as well, it was set to ‘text’ instead of ‘json’ not sure whether that makes a difference but for my examples above I changed it to ‘json’.

Summary:

After disabling DESS battery balancing (`isPeriodicFullChargeOn: false`), any PATCH to dynamic-ess-settings via VRM API node (e.g. buyPriceSchedule) fails with:

```json
{
  "success": false,
  "error_code": "validation_error",
  "errors": {
    "periodicFullChargeInterval": "periodicFullChargeInterval should be null"
  }
}

```

GET shows `periodicFullChargeInterval: 15` (and duration 2) even after PATCH with null values; the nulls do not persist. Other fields like fullChargeInterval remain. The validation blocks all PATCHes once balancing is off. Workarounds discussed: always include `{"isPeriodicFullChargeOn": false, "periodicFullChargeDuration": null, "periodicFullChargeInterval": null}` in every payload, or set large interval values.

**Victron GitHub analysis:**  
No public source for the VRM API backend validation logic (proprietary; [vrmapi.victronenergy.com](http://vrmapi.victronenergy.com) endpoints).

- [GitHub - victronenergy/dynamic-ess · GitHub](https://github.com/victronenergy/dynamic-ess) contains only the open-source Node-RED DESS flows/scheduler (D-Bus writes for /Settings/DynamicESS/_, no periodicFullCharge_ fields, no VRM PATCH validation).
- [GitHub - dirkjanfaber/victron-vrm-api: Interface with the Victron Energy VRM API · GitHub](https://github.com/dirkjanfaber/victron-vrm-api) is the Node-RED client node only (no server-side code; related issues mention similar periodicFullChargeDuration problems).
- Other repos (vrm-api-python-client etc.) are clients.

The bug is an overly critical (non-optional) validation check in the closed-source VRM API for partial PATCHes to dynamic-ess-settings. It enforces `periodicFullChargeInterval: null` strictly when balancing is disabled, breaking API usability for other DESS config changes. No fix visible in public repos.

This is a good find and seems to be a bug. Still need to figure out if that is on the node side or more on the API side itself. I’ll look into it.

This should be fixed now (on the API side). Disabled balancing is now correctly set to `-1`, instead of to `null`, which resulted in some weird behaviour.

Thanks. Could you elaborate a bit on what are now the correct values to set to enable/disable PFC (PeriodicFullCharge a.k.a. ‘balancing’)?

For VRM-API in a Node-RED flow such as here:

> [@Can't use VRM API node after disabling DESS battery balancing](https://community.victronenergy.com/t/cant-use-vrm-api-node-after-disabling-dess-battery-balancing/57596/5):
>
> I do not need the API to patch config currently. If you give me a (harmless) json to inject I can test for you. Back then I was testing isScheduleSocOn, scheduledSocGoal, scheduledSocTime that is a) not implemented and b) does require 0, null, null respectively. You know, the infamous b\_goal\_SoC and b\_goal\_hour port from Node-RED DESS that I am catching so much heat on for requesting it for over a year already, and what we now ‘emulate’ by setting virtual forecast adjustments.wink EDIT: fou…
