question

• Ruuvis: include status info in transmission to VRM, needed to fix hanging sensors on VRM Dashboard and other places in VRM.

The hanging sensor still show on VRM Dashboard. Unit in the GUI is now hPa, on VRM still kPa.

The Remote Console (via LAN) hotkeys are messed up (more precisely, the arrow-left button is not properly aligned and has no arrow on it, but it still works) after I updated to v2.80~36 (from v2.80~33):

Used browser: Firefox 95.0.2

Update:

Now the hotkeys are displayed properly.

I don't know why. I did not changed anything. No reboot or anything else.

AC-loads is not been shown on VRM anymore. On CERBO it's all fine but VRM shows nothing

Is this screen right?

L1 shows 222.1V x 14.3A which should equal 3.175kW, not 1.275 kW? And Battery charging value is 2.048 kW which exceeds the Generator value?

Previously VRM was not using beta firmware and yet the Dashboard has shown these strange kinds of generator and battery charging values since the system was installed in August. We were advised by distributor to try the beta. Started with v2.80~24 and just upgraded to v2.80~36, but generator values (as below) still seem very odd/wrong.

Small home, 100% off grid installation.

9.7kW of solar and a large lead acid battery bank.

2x MPPT’s

2x 5kVA Multiplus II in parallel

Color Control GX

SmartShunt Battery monitor - we feel fairly confident we have pretty good parameters set in here, ie used the Peukert calculator, etc.

VE configure settings for both master and non-master Multiplus II:

AC input current limit - 7.3 amps (in each multi), override by remote unticked (VRM showing 14.5 in current limit)

Dynamic Current Limiting ticked

Power Assist - ticked

UPS - unticked

Weak AC - ticked

Grateful for any explanation.

On Venus OS version 2.73 On the VRM dashboard display, I have the location of my Fronius Grid Inverter Galvo 2.0 (single-phase) showing up on MulitPlus II Output when the setup of the Cerbo is configured to be on the Position menu MultiPlusII  AC Input 1 (where it is installed).  Has this been addressed in 2.8x?  The Fronius Galvo 2.0 is connected via the wifi network to the Cerbo. 

In the below Dashboard display as you can see the MultiPlus is in the inverting mode and supplying the load with the PV inverter power showing up as a load instead of a Grid export.

(The other confusing issue which seems to not be related to the PV inverter, is that I have two ET340 (3phase) energy meters address #1 AC Input and #2 AC loads installed as shown on the dashboard.)

Venus OS 2.73 Pylontech UP2500 (24V) battery (new 2021), Remote console, Pylontech Battery, Details menu.

The image shows two problems;

1. the Lowest and Highest cell voltage readings are reversed, this reversal also applies to the data which VRM stores on the cloud and the UI on the advanced graphing of max& min cell voltages.

2. the reported cell temperatures are being reported wrongly and again reversed (as with the voltage) when translated to the correct real temperatures.

a) the temperature is incrementing in 10C steps, not 1 degree

b) the correct temperature readings as far as I can tell should be 27C = 7C (reported), 28C = 17C (reported)

I can download the correct data directly from the battery using Pylontech Battery View software, it would just seem that Venus OS is not displaying the correct cell temperature data as downloaded from the battery BMS RS485 bus, all the other readings seems to be correct i.e. battery voltage, current and charge/discharge limits. It is really disturbing to see in winter when it is 12C readings of -150C!

How this helps to get to correct the issue, keep up the great work.

Ruuvi tags working well with GuiMods on v2.80~36

I found I can only have one bluetooth dongle at a time connected to the CCGX, and have to reboot to change dongles. Is it possible to allow two bluetooth dongles to be connected at once? This would allow me to monitor temperatures at both ends of our 38m Spits, the battery chest tag doesn't reach if I place it that far away at the moment :(

I did find the CCGX rebooted itself twice yesterday, but I've not seen it happen today, and that could also be related to my GuiMods install, I'll update if it happens again.

Hi,

I have a new Cerbo GX (v2.73). Bluetooth stopped working after 2 weeks so I did a factory reset using a USB today. This fixed the bluetooth. I then immediately upgraded to v2.80~36 and the bluetooth stopped working again. I did a factory reset on new firmware but still no bluetooth (blue light remains off even though it is enabled in settings). I reverted back to v2.73 and v2.72 with factory resets but still no bluetooth. In bluetooth settings the pincode remains blank and I cannot input a number. Refer attached.

Could going to v2.80~36 cause the bluetooth to stop working for good? Any advice would be appreciated!

I'm trying the temperature-controlled relay functionality, and have a battery post sensor, as well as two Ruuvi's (which are AWESOME!). However, after having specified 'Temperature' as the control for relay 1 on my Cerbo GX, I go to the 'Temperature' menu, but am presented with a blank screen:

The sensors are visible at the top level menu, and also on VRM, so perhaps this is a bug/regression?

I seem to notice an irregularity between VRM power consumption in the overview vs what the advanced battery and AC output graphs are showing, I think the advanced graphs are correct but the overview is higher, for instance last night between 4am-5am the lowest discharge was 280W (so average was less) but the overview shows almost double at 0.50kWh. With my total consumption for Today; midnight until now, 5.6kWh which is a lot more than normal / expected.

DVCC Limit Charge Current Behaviour

Loving the new mods in 2.80~36. Not sure if this is a bug or partially implemented but when I enable DVCC Limit Charge Current setting the MPPTs go into External Control - is this the intended behaviour? Also, this also forces the MPPTs into Bulk charge mode irrespective of current. Turning Limit Charge Current off returns control to the MPPT internal algorithm. This happens irrespective of the Multiplus II being on or off. My batteries are unmanaged AGM, I do not have a BMS and there are no Assistants configured on the Multipus II. I haven't regression tested this but thought it was worth flagging as this does not match the documented management of charge algorithms when using DVCC with unmanaged batteries. SVS, STS and SCS all work as expected.

Config

Cerbo GX, Multiplus II, 2 x MPPT VE.CAN 150/85 rev 2 (VE.Can bus), Lynx Shunt (VE.Can bus), 2 x Smart Shunt (DC Energy Meter (DC System & Alternator), 12 V 1280 AH AGM Batteries.

All firmware is up to date.

How to remove Ruuvi tags?

I changed some of my Ruuvi tags from 3 in one to 4 in one models. The new ones work excellently and values: Temp, Humidity & Air Pressure are visible in VRM.

Removed Ruuvi tags are also visible in VRM and I don't know how to remove them.

I first deactivated Ruuvi tags to be removed in Cerbo IO settings and then powered them off, this removed them comletely from Cerbo's display screens. But not from VRM, removed devices are also not visible in "Device list" in VRM so they can't be removed via that.

Removed sensors are still listed in Dashboard and selectable from Advanced view.

By the way, it would be good functionality to be able to select which temp sensors are visible in the dasboard, for example I have quite many of them in this installation, and maybe it would be good to not have all always on the dashboard.

Now I see all 9 active sensors + 3 already removed ones with outdated data.

I burned venus-image-raspberrypi2-20220103133553-v2.80~36.rootfs.wic.gz to SD and booted a Raspberry Pi.

I opened http://venus.local/ in browser and saw:

Remote console
Failed to connect. Make sure to enable Remote
Console for LAN, and reboot the device.

What's wrong?

energy flow looks strange

Hi!
Just got a Carlo Gavazzi EM112, and has been trying it out as an AC Load monitor on my boat. It is placed just after the main switch, and it is measuring the total load of the water heater, a electrical stove, an auxiliary outlet, as well as a multiplus. The idea is to get a picture of the total energy of shore power used, not just what is passing through the multiplus.

Haven't seen any info of really what to expect, but here are my findings so far:

After adding the monitor, it seems to show up under Settings, Energy meters, where it cannot be renamed or removed. As of roles, AC load seems to be called "AC meter" instead of "AC load".

In the main menu, the same meter appear, this time with what seems to be correct values, and also a device menu with possibility to rename the monitor:

Under setup and role, at this instance the role is called "AC Load", not "AC meter" as in the first instance.

* I cannot find the corresponding measurements in VRM portal. Not sure if I am supposed to yet? I am hoping to be able to get the following: Voltage, Current, Watt, Hz, Ah, Wh.

I am also wishing for a optional separate square on the GX main menu with the current load for this meter.
