M-bus (ModBus) interface

[Gilles]

Hello,

 

I have equipped my apartment with multiple wifi Shelly modules to manage it entirely.
I have 4 meters (1 x hot water, 1 x cold water, 2 x heating) which have a 3-wire M-Bus (ModBus) link.
- Is there a Shelly accessory I can connect to these meters ?
- Can Shelly cloud store the data read by these meters (e.g. every day), so that it can be consulted retrospectively for a specific date ?

 

Thanks in advance for your help.

I think M-Bus (meter bus) and Modbus are two different bus systems.
But the fact is that Shelly only supports Modbus TCP and acts as a server (makes some data points readable and available to external systems).
You would need a Shelly Modbus client function, which is not implemented.

The best thing to do is to ask this question to the Shelly Support.
