Elcom i2 Bus (BVM-100)

[JJG (Jens)]

Someone an idea how I can manage an integration like this with an BVF 200?

[Schiemanskie (Florian)]

Hi Jens - I would go with an RSR-220 Relay and set it up just like the the audio only BFT200 Handhelds.

Elcom RSR-220 Rufrelais für Innenstation Video BVF-200 EB 6D-Video 1901820...

Something like things.

[sailor (Justus)]

Good evening dear all,

this topic got really confusing for a beginner like me, so I am trying to explain the situation that I have at home:

I live in an appartment, with the ELCOM BVM 100-ws installed, including the video screen, but no repeater so far.

Main functionality required: ring the door bell on the entrance door, and have the entrance door opened by nuki opener sequential to this.

Maybe, somebody can be so kind to explain me in detail, what I need to buy, and how I am supposed to connect everything in order to make it work. A drawing would be lovely!

Thank you so much!

Does somebody have an idea?

I really rely on some assistance here…

[Jeromae (Jerome Schenker)]

Hey,

I‘d ne nice if somebody could please sum this up or even do a little manual for the BHT-200. I really want to integrate it into my smart Home.

Thanks

Hi Jerome,

see following posts:
General first working setups by Thyraz and Florian with general setup + wiring Pictures:

Hi Tobias , thanks for your hint regarding BFT-200 connection. I am using the BHT-200 which should have the same hardware setup :). If I understood you correctly you did the following: [BHT200_Opener] you replaced the original board from the BFT-200 with the RSR-200, everything else is connected as original Then you connected the Nuki Opener to the utton contacts for the open button from the BFT-200 Could you please share which cable colors of the Nuki Opener were connected to the RSR-200…

Elcom i2 Bus (BVM-100)

Hi Florian, yes I replaced the orginal Board with the RSR-200 like described in your photo. Then I used the 2 big pads of the button (on the backside of the circuit board where the red arrow in your photos points to. To solder cables to the pads, I removed the dark coating with a cutter knive. For the wiring look at the section “Analogue intercoms” in this document: You need yellow (ring detection), blue (door open signal) and purple (GND). Between yellow and purple there’s an optocoupl…

Elcom i2 Bus (BVM-100)

Hi Florian, maybe this helps to clarify it: [Opener] The relay contact in the Opener is used to simulate the button press on the intercom. As the purple wire is also used as GND signal for the ring detection, we connect it to the pad of the button that is connected to GND on the circuit board. This way the Opener already has the GND signal to measure Voltage on it’s ring detection input (yellow wire). Now we need a voltage that we can measure when the intercom is ringing. The easiest way…

My working setup with some pictures:

Elcom i2 Bus (BVM-100)

So I finally got it running with my Elcom BHT200! Things needed: BSR-200 Module as stated by Tobias and also Florian, thank you guys! I soldered 2 cables on the front connections of the board (Blue and Purple Cable) you don’t need to solder it on the backside with the black coating. Ring detection yellow to BUS+ as already mentioned but make sure to follow the procedure in the app precisely! (Ring - door not open - Ring etc. To let the Nuki learn the different voltages) I am writing on my p…

But you are right, maybe we should go on and have a better summary in place

[sailor (Justus)]

Hey Florian,

any chance you can support me with my BVM-100?

Thank you!

[Schiemanskie (Florian)]

I am sorry I don’t have a BVM to test things out.

edit:
I looked up the manual for the BVM-100 and searched for an Call-Relay that could be used. I am sorry to say, but there seems to be no “plug-in” solution for you at the moment.
Only the BVM-200 handtelephone seems to have an option to upgrade it with an call-relay.

So official upgrade for the following handhelds are the following:
BHT-200 / BFT-200 → get an RSR-200 and read the thread again
BFT-210 / BFT-510 → get an RSR-210 and read the thread again
BVF-200 > RSR-220
BHT-200 / BHT-280 / BFT-200 → RSR-500 for usage with an external telephone

BVM-100 → nothing yet? somebody try to squeeze an RSR-200 into it and try to use it with the intercom?

Dear all,

is anyone out there who modified the ELCOM BVF-210 WS successfully respectively any first ideas on that?!

Many thanks in advance

BVF-210 WS

[d025477 (Axel Jebens)]

See how you can configure the system (bell ring panel at the door) to let you open the door in case nobody rings before. See item (2) switch 2. Maybe you can get access to it, but if you don’t own it, you may check woth the other property owners.

Hey,
someone got it working for BVF-510 ? exist there any Relais too ?

[Ben]

i talked with the Technical Support from Elcom.
The Elcom red114y relais convert the open signal to bus command.

[gizmo (Jean)]

Would that mean two relais? One to convert bus to signal to trigerr the Opener and the later to convert open signal to bus?

If so, could we use that solution without starting conversation (for setup which requires it)?

[Ben]

i bought the elcom red114y relais and waiting for my nuki opener… i will test it next week.
Nuki opener → elcom red114y → Bus Signal

XX = BUS
ctrl-in = open signal from nuke opener

[gizmo (Jean)]

But then no ring to open, right?

[Ben]

For Elcom BVF-510 it works.

[gizmo (Jean)]

Hi Ben,

Many Thanks for sharing. May i ask u a couple of details:

• in normal operation does the opening of the door requires a 2 way communication in your setup?
• any particular reason to have used the green (and not the yellow) connection for the ring detection?
• is the Opener set up in general bus or analog?

[Ben]

in normal operation does the opening of the door requires a 2 way communication in your setup? = no
any particular reason to have used the green (and not the yellow) connection for the ring detection? = both cable works
is the Opener set up in general bus or analog? = analog

[perler (Pat Erler)]

ok, after connecting the BHT-200 using the replacement module RSR-200 (and reactivating old soldering skills) I can open the door via the app. but it doesn’t ring. and I cannot open the door with the button on the (hardware-) opener.

This is what I have done, maybe someone spots the error:

1. connected yellow to K on the RSR-200
2. made a bridge from K to B (*1) on the RSR-200
3. connected purple to ground on the main board
4. connected blue to “open door” (other side of the button) on the main board
5. set up the opener as “generic|analogue” in the app

*1
thyraz’ hand written scheme shows K to a, a picture of florians shows K to b (the lowermost jack), so I am not sure what’s right.

any advice would be appreciated.

[gizmo (Jean)]

Got it finally working with a rather complex but functional setup:

• my old BVM100 on a building where normally opening requires 2 way communication
• a BSR200 relay to trigger the ring detection
• a red114y relay to open the door

with this setup both direct open and ring to open functions do work

ok, now have to tidy up my draft cabling and find a nice way to hide both relays in a junction box

ThanX to all
