Thanks Rick. HTTP calls will work great for me.

@Rick this is indeed good news. Any idea on the timing?

Peter, I will answer your tech questions here 1)  WiFi values can be read using HTTP get calls.  There is another thread on this forum with info and others who are doing it.  You wi...

With all of the recent changes to the WS500 firmware we have decided to sunset this product development.  We suggest you use the android tool available from Wakespeed for firmware updates.&nbs...

This is what we got back, which is encouraging and keep in mind that the Master uses firmware that is keyed to the serial #, and has to be requested from engineering. WCIB does not work on Ma...

Sorry, 35€ is more like US$38, not $37.

@tine Thank you for your fast and detailed reply!  May I ask what is the "RC" component? "C" as in capacitance?  Based on your advice, I will disable the Neey balancer and only use it i...

Well we can write the code for 2 Serial Slaves for SMA SI. We have it for Victron already. I strongly advise not to use Neey BMS in conjunction with REC. This is why: it introduces measuring err...

I have the configuration tool version 1.2.2 and when I try to update the firmware from 2.5 to 2.6 the program just closes down and the update file is not sent to the wakespeed.  Is version 1.2...

Hey Bill, I am not sure if the Master supports this new function but will check with engineering and report back.

Hi Rick, thanks for the response. Here is a screenshot of the 9m SW/HW. I've checked the website and unless I am missing something, do not see any newer firmware. It will great to be able to see wh...

Hello Tine, Thank you for your reply. Now it is 9 months later and I am finally installing my battery system. I had bought the surplus ("new-old-stock") LTO cells several years ago, so changing t...

Bill, I looked over your parameters and in my opinion, they are pushing the limits on both the high and low voltage side. Between 3.5 and 3.7V there is only 1-2% capacity so I would tend to be a bi...

@Ben I've looked across all of the documentation and tried to use WCIB? but the command is not recognized in the manual command line. 

Your question:1. I cant explain you, I don't know this in detail.  But the 3part manual page you post don't sound correct to me. I never have seen this document, no time at the moment to study...

Hello, I have been using my REC-BMS setup with the following settings for the past month. Some of the settings that my electrical engineer designer has specified are different than what I've seen i...

@Rick Thanks.  Got it.

The cable is custom assembed and comes as part of the REC BMS software kit. You can buy it here. https://ogm-energy.com/products/rec-pc-software

My contractor installed my REC BMS and batteries but didn't leave the cable. Is there an amazon link for a suitable config cable? Thanks  

@Rick Thanks Rick.  I cleaned it up with alcohol and it appears to be a circuit board fuse, because there is an "F1" next to it.  So I guess I need to know what fuse it would require. See...

Great, glad you got it working.  For reference, if you want to move to the VE.CAN port here is a quick video to help setup the BMS and the Cerbo. https://ogm-energy.com/community/ogm-user-for...

Hey Mike, REC is pretty good about sharing this info so by way of this message I have included Tine in the thread and hopefully he can help you here. @Tine Andrejasic 

With recent upgrades of the Venus/Cerbo firmware to 3.3X and REC-BMS 2Q Firmware 1.5 the REC 2Q BMS will now work properly on the Victron VE. CAN port instead of using the BMS.CAN port.  This ...

Hey guys.  I have a two battery (electric boat) that uses a REC master and two slaves.  There are no LED lights anywhere even though the master has 61VDC.  Desperate, I took apart th...

A full reset, completely powering off the REC, resolved it.

Yeah, it's still not happy: I don't see any packets there, from the REC, eh?

@Rick I figured that… I reset CHRG to 1, CANS is still 3 which I believe to be correct for the Cerbo's 500 kbit CAN-BMS port. Still nothing, unless I need to reset/reboot something to get t...

Try resetting the CHRG and CANS parameters.  Details are in the new manual on the rec-bms-na.com site

Any idea why I would have lost the CAN comms between the BMS and the Cerbo GX when I upgraded to firmware v1.5? I didn't change anything else. A.

Here is some feedback from REC engineering that may address your challenge while giving you a level of system redundancy at the same time.  Hope it helps I would go with 2 parallel systems.&n...

Here is something that may help.  I havent had a chance to check it out myself yet. ## PLACEHOLDERS Use __BACKTICK__ to use placeholders that are listed below. You can type in a __BACKTICK...

@Rick awesome, do you have any details on how and what to query the wifi module?   is there a list of URL syntax? i just want the individual cells, temp, amps etc

Sure, you can query the Wifi module or use the RS485.  The RS485 protocol is covered in the manual. I have a request in to enginerring for a list of http variables available and will post it ...

Has anyone played with getting data out of the ABMS either via RS485 or via Wifi module web server queries to home assistant. ideally, I would like to get realtime battery health and individual ce...

Good day everyone, I hope all is well.   To begin with, OGM staff please note this is a rough duplicate of a contact form I submitted. I realized after submitting the form that posting here...

Check out this one.  It may assist with many of your queries. And don't forget, these are all available in editable versions too. https://rec-bms-na.com/system-design-ideas/#48-50-wpfd-marin...

Greetings all. I am configuring and integrating a LiFePo4 stans alone 3P4S 12V (942 Ah) with REC Active MBS w/wifi and precharge in my current system which I describe at the bottom. I am looking ...

Yes, it is a high-voltage system. Nevertheless, it should be possible to reach the two slaves. So far without success?

for most operations you connect to the Master to retreive all slave parameters, not to the slave.  Only things like slave firmware updates .  I see that your pack voltage is 104 volts so ...
