BMV712 temperature sensor and status not working

I got a temperature sensor on my BMV712, but no matter what I try in settings, it shows nothing like it's not connected.

I got another one from the store to see if it maybe broken but that one gave the same result.

Other issue.....after a little while BMV712 shows load drops to 0% in a couple hours after charging, but the 4x 12V220Ah agm's are fully loaded.( New batteries)

Can it be a broken print on the shunt or is the BMV itself broken?

Everything else seems to be working fine...

Why do I get "reverse polarity" when connecting a PT100 temp sensor to Cerbo GX?

I'm planning to connect several temperature sensors to my Cerbo GX to monitor engine room temperature, fridge, freezer and sea water. However, when connecting my first PT100 element to my Cerbo, it only states "Reverse polarity" as status and no temperature. I have checked the PT100 element, and it works well. I have also tried to switch polarity on the connectors, but still it does not work. In the status it also states 4,2V, which is strange as it should state resistance. Any clues?

Temperature probe output location

I am upgrading my electrical system on my boat and have the following VE equipment:

2 X Lithium Smart 12.8v 200 amp batteries

BMV-712

Multiplus 120v 3000 12 Charger/Inverter

Cerbo GX with touch 50

BMS CL 100 12

My question is where the temp probe should sit. I currently have it oFr my multiplus with 2 positive wires running from my shunt to service and engine battery. The schematic I got from my Victron installer indicated the temp probe should come off the shunt? If I do that how do I feed my 712 readout with battery info And power?

Is it possible to visualize temperature sensors on the new VRM dashboard?

Very nice with the new VRM dashboard. Really love it, but temperature sensors are still missing. Any plans for adding that feature, and is there any way I can add temperature sensors myself to the dashboard? Just some simple indicators or scorecard showing name of sensor and temperature would suffice.

High hopes for this feature. It would complete the current dashboard.

What is the temperture measurement accuracy of Victron sensors?

I've purchased a new MulitPlus II with included battery temperature sensor but the sensor is reading many degrees high, while I'll be using the sensor on LifePO4 batteries the low-temperature reading is the most critical in my situation. What accuracy should I be expecting from Victron temperature sensors?

Can the temperature sensor be corrected with software?

What temperate sensor is glued into the battery sensor? is it just a simple LM335?

Temperature Sensor with Cerbo GX and touch 50

Hi, I'm using a temperature sensor (ASS000001000) connected to the Victron Cerbo GX to measure the ambient temperature in one of the cargo bays in my vehicle. Two questions:

1) How do I configure the Victron Cerbo GX to show Fahrenheit instead of Celsius on the Touch 50?

2) The sensor is showing about 5 degrees higher than measured with other temperature devices. Probably because of its placement. Is there a way to adjust the display so it will display the actual ambient temperature? I would like to keep the sensor it its current place.

Thank you!

VRM+BMV712 - No Batt Temp

I have recently hooked up my BMV712/MPPT Solar to VRM portal via VenusOS - its really great and loving it so far.

I have battery temp being fed into the network by Smart Battery temp sensors. And this works as I can see Batt Temp on the solar? (or was it the BMV?)

Anyway - I was wondering if I am doing something wrong as despite the battery temp being on the network, it is not passed through to VRM.

Venus GX temperature inputs

There are two temperature inputs on the Venus GX, but there is not much information about them in the manual. Are these only for the Victron battery temperature probes or can I connect another temperature sensor to them, like for monitoring for example room temperature, and if so, what kind of sensors will work (types like PT100, PT 1000 etc.)?

Analog engine data to NMEA2000 using the Cerbo GX?

I am planning to get a lot more data to my NMEA2000 network. I have just ordered a Cerbo GX and planning to get water tank, fuel tank and septic tank data to the NMEA2000 network using the resistive tank level inputs on the Cerbo GX and the VE.Can to NMEA 2000-adapter.


My engine is a VolvoPenta MD2040 and a bit older engine without support for J1939. I am also considering several options such as EMU-1 from Actisense. But want to see if I could find a simpler solution instead.


I want to get the following data from the engine to the NMEA2000 network, hopefully using the Cerbo GX.

  • Tachometer/RPM data from alternator
  • Oil pressure
  • Engine temperature


Is there any option to get engine data to the NMEA2000 network using the different tank, temperature and digital inputs on the Cerbo GX?

Old Multiplus low temperature cutoff

I have an old Multiplus 24/3000/70 (still has VE-Bus, it's the 19xxxx model), a BMV 712 and a 30a smartsolar MPPT. I've purchased a large "drop-in" LiFePO4 battery with no LT cutoff and no external comms. Can anyone assist with low temperature cut off?

- I know how to do this with the MPPT - (either by using a temperature sensor to BMV712 or using a Smart Sense and linking with Bluetooth.

- The question is, how do I cut off the Multiplus (someone accidentally turns generator on to charge for instance and it's below 5 degrees in battery compartment. Do I use the same sensor and use an assistant and 2 wires (not sure how this works) from the BMV 712? Should I use a smart sense bluetooth connection for MPPT and a separate wired temperature sensor?

Any help would be really appreciated.

Low temperature cutoff for Smart MPPT and Quattro ?

I have a Quattro and Smart MPPT. Both would be normally connected over winter. I'm planning to have LiFePO4 batteries and want low temp charging cutoff for less than 5DegC. I also have a BMV-700 and am planning to integrate with a CCGX.
Can 1 temperature sensor tell both the Quattro and MPPT to stop charging below my cutoff ?
Which temp sensor and how/where should it be connected ? Or am I best getting 2 sensors one for the Quattro direct and one for the Smart MPPT.

MultiPlus 12/3000/120-50 120 Temperature Sense error and Battery Temperature alarm

I have an ongoing problem with what seems to be erroneous High Temperature alarms on the Multiplus 12/3000/120-50.

The unit details:


Product
MultiPlus 12/3000/120-50 120V

Firmware version 475

Last connection 5 minutes ago

Product id 2702

VE.Bus connection VE.Bus

Hardware configuration Single unit

VRM instance 0


Things I've done to troubleshoot:

-- checked all terminal connections... everything is tight.

-- manually measured surface temperature of multiplus, which ranges between 20C and 30C.

-- upgraded firmware to latest version

-- temp alarm doesn't seem to have a pattern for which it gets tripped. When the alarm goes off, there doesn't seem to be excessive load on the system.

-- I observed that the fan on the unit does not come on and I thought it was a faulty fan. I added a large load to the system by turning on the AC unit when inverting and the fan promptly came on. So, I'm thinking the fan is working as it should.

-- the unit is installed in a bench seating area, which is enclosed. I thought ventilation was a problem, so I added 4 cooling fans and external ventilation, still received alarms.

Any ideas on what else to check?

When I added the bluetooth sensor and apired it the att will not conntect to the MPPT any more. It appears in the app but grayued out. It seem to be a conflict with the bluetooth on both devices (MAC ID issue maybe). When I remove the power from the battery sensor the MPPT appears to work fine.

(Thermal Runaway?) VE.Smart Network Support on Blue Smart Charger IP67

Pretty sure this was asked a few years ago but wondering if anything has changed...

Any chance of VE.Smart Network coming available to the Blue Smart IP67 chargers?

Could really use that actual Battery Temperature reading...on these cool sunny days right now the ambient temp of the charger outside in the shade and the temp of the battery in a black plastic box is quite a big spread after a big charge (88f vs 61f - I think..the Blue Smart doesn't actually show temp- Another feature request to display Blue Smart temp?)

This leaves the MPPT on the VE.Smart Network to think that we are overcharging because it has temp compensated the voltage down for the warm battery (its probably right) while the BlueSmart IP67 is doing the opposite and temp compensating up for the cool charger.
