Using Serial Data Source as MBUS device
-
@MattFox So: Turns out the socat solution works, but it's not really as straightforward as using the Serial device natively:
Can you poke around and see if the Serial data source needs some hugs? Using a TCP forward for a USB converter serial port seems a bit silly to me, when Mango has a raw Serial device interface that (should) do the same thing.I've now had no luck with the serial data source on my ARM based IMX8 machine over hardware serial or USB to 485 serial under V3 or V4, and now am seeing the same thing under V4 on a raspberry pi.
I'm happy to set up a screen share / demo video / something if you want to see what I'm seeing with this.
Thanks for your help, in any event, as we now have a (mostly) working MBus data source again, although in a somewhat ridiculously rube-goldbergesque way.
-
@Turbo sure I'll flick you a PM
-
@Turbo can you share the reason why you didn't use a Mbus to Modbus TCP converter in your cases? The only time I have to reqd data from Mbus devices, I use Anybus gateway, quite easy to use.
-
@tungthanh500 Budgets. The M-Bus to USB converter is $20, the M-Bus to modbus device is considerably more expensive. Our goal is also to keep the number of things "needing configuration" to an absolutely minimum:If we can do it in Mango, it saves us time and money (and spare parts inventory costs).

@Turbo
I didn't notice the MBUS driver has been dropped. That is bit disappointing. I have got a project with 50 MBUS meters. So I have to hook them into something else then spit them back out via BACnet IP then.the workaround you have mentioned is a bit painful to implement and to get working reliably.
-
@cwangv That's true- I'm happy to send you my code, if you want, when I get it working- It's just a scripted point that searches raw strings for the OBIS code and saves it in datapoints. This for energy meters, and so far, it works OK.
@CraigWeb any plans on bringing the M-Bus module in Mango V4? It's interesting, since it's still stated as "supported" on Mango's website: https://radixiot.com/supported-protocols
You only find out it's missing from V4 when you look at the documentation for Upgrade from V03 -> V04: https://docs-v4.radixiot.com/upgrade-to-v4 and scroll down to "unsupported modules"
-
@Turbo you arr right, I bought a converter at $500 in my country just for 4 water meter
-
@Turbo I think you would be better off chatting with our team about adding the data source back to v4. We removed it because we had a total of 5 downloads over 3 years.
-
@CraigWeb I appreciate that; We're going to be shipping a mountain of these things internationally use M-Bus (I hope), so for now I'm using my TCP silly workaround for this (since the Serial data source still appears to not work properly for whatever reason on our Arm-based machines).
Some other folks have piped up here as well about M-Bus- This exists basically nowhere in the US (as I've found now that I'm testing things using M-Bus) but apparently is quite common in IOT purposes in Europe- Every meter in Norway (for example) has an M-Bus port for interfacing HAN devices directly to your buildings' meter.
Surely someone must have had a reason that this got added in the first place; Although I do understand not updating things if nobody is using it. Since we're going to be using this A Lot (I think), we may be able to chat NRE to get it put back- I'm still chatting with Michael about Mango for our 2023 project pipeline, and this could be a good business discussion point to have.
-
@Turbo ye I know of one other client in Ireland who is using it successfully in v3 with about 30 MangoGTs so ill help motivates it with that point.

@CraigWeb
Hi, Craig
Good to see you back on here.I will definitely submit this for my project since I have an existing Mango system running.
Should I just get in contact with technical support?
