Hass 2021.6 not loading vbus

[thwandi]

Hey,

i have tried to setup the Vbus custom component in my Hass but it keeps mentioning the Following. Im not getting any data out of the vbus, the entities are just showing "Unknown" and nothing happens. I Connected the vbus using a USB to RS485 adapter. may that be the issue why i am not getting any data? Or is it regarding the last Hass Update?

A few questions:

• which version of Home Assistant are you using (2021.6 is not out yet I think)?
• was it working before? or is it the first time you are trying?
• what type of Resol/Vbus component are you trying to communicate with?

I'm using core-2021.4.5 and it is the first time i tried it. I have a Deltasol BS Controller and a USB-RS485 Converter on the Raspberry which is running the HA. Im thinking that the RS485 Adapter (it shows as USB to UART CP2102) is not the correct choice for getting the Vbus working.

What did you put inside your YAML?

Also - I think you are correct that VBUS is not the same as RS485.
They are similar but I don't think they are compatible.

How did you connect your vbus devices to Homeassistant? I dont wanna use their own converter stuff because its too expensive.

My yaml for the testing is as follows:

`- platform: resolvbus

I use this product (got it almost 10 years ago!): https://www.resol.de/fr/produktdetail/13

Hi,

so i now changed to a classical USB UART converter and a level shifter circuit. If i connect that to my Mac and Readout the Serial Stream it shows the Following:

aa1000204710000112651554452d032164004e02004b7f002c04014f000040feff64000000001b3f0800000038450800000032808044f78f00000000007f00000000007f00000000007f00000000c001bcffaa150020471000010a6802010000007c64004e02004b7f0071580d2a018400fafeff64004e02004b00000000007f010b000000730000000080ff

AA is the start, 0010 should be the destination address, 4720 should be the source address, so far so good. But if im connection that to my Rpi with Homeassistant OS it still says "unknown" for all my configured sensors. My Controller is a Deltasol BS HE, 4720 in the resol list is known as BS/2 HE.

But im still not able to see any data from the Controller in my Homeassistant. Could you help me? Is there a way to monitor if the Serial Stream is arriving in the HASS correctly?

Thanks!

Last year I decided to upgrade my RPI for HA, and to keep the old one for owserver, teleinfo and resol communicating with HA over the network. I therefore no longer use this HA component and it's possible that it is no longer compatible with latest HA versions...

I think the first step is to ensure that you can read the RESOL data directly from the command line.
I have attached here a small python script which I use for checking values.
vitosolic-test.zip

On line 8, you should change the USB port.
On lines 29-32, you should change to b'\x10\x00\x20\x47'
Then on lines 142-174, you can change to use the correct sensors
