Http Api command to Zennio Getface IP - Evens - 14.05.2018

Hi,
 
On a project I’m working on, we have a kNX switch that shall open a lock, in the main door of a house. The video intercom device is a Zennio Getface IP. I want to use the LM5 lite that I already have, to be used as a gateway. To my knowledge the Zennio Getface Ip has Http Api license installed.

Is it possible to do? And if so can someone help me?
LM5 ip:                                 192.168.1.103
Zennio Getface ip:           192.168.1.101   
 
See link below for manual to Zennio Getface IP:
http://zennio.com/video-intercom/getface-ip-en/getface-basic-unit

Best Regard.

Do you have documentation on HTTP API? Sending requests via HTTP is simple, but without documentation there's nothing we can help with.

Hi,

Attach this code to an event script (boolean object). It will contol switch 1 depending on object value. Make sure that Switch API is enabled without encryption and authentication. log(...) call at the end should be removed if script is working correctly.

Code:
require('socket.http')

switch = 1

value = event.getvalue()
if value then
  action = 'on'
else
  action = 'off'
end

url = 'http://192.168.1.101/api/switch/ctrl?switch=' .. switch .. '&action=' .. action
res, err = socket.http.request(url)

log(res, err)

Hi

Works perfectly, thanks! Smile

Now to my next question, how to read a input from Zennio Getface IP ? 
is there an easy way?

RE: Http Api command to Zennio Getface IP - admin - 18.05.2018

State has to be polled so you need a resident script. Adjust sleep time as needed, but do not use 0 as it will consume all CPU.
Uncomment and modify grp calls depending on how many inputs are used.
Code:
require('json')
require('socket.http')

res, err = socket.http.request('http://192.168.1.101/api/io/status')
if res then
  data = json.pdecode(res)

  if type(data) == 'table' then
    ports = data.result.ports
    log(ports)
    -- grp.checkwrite('1/1/1', ports[ 1 ].state)
    -- grp.checkwrite('1/1/1', ports[ 2 ].state)
  else
    alert('failed to decode data')
  end
else
  alert('http request failed ' .. tostring(err))
end

-- release unused resources
collectgarbage('collect')

Hi Admin,

Thank you! 

It kinda works, but not 100%.

When triggering input1 nothing happens.
When triggering ext1.input1 port 2 goes to ON.
When triggering ext1.input2 nothing happens

Im not shure if it`s the Getface that is the problem or what? do you have an idea?

From current errors:

Test Script Getface 18.05.2018 10:21:51
Resident script:9: attempt to index field 'result' (a nil value)

You access the same URL (http://192.168.1.101/api/io/status) in your browser and check whether input states change or not.
Error checking can be improved like this:
Code:
if type(data) == 'table' and type(data.result) == 'table' and type(data.result.ports) == 'table' then
    ports = data.result.ports

Hi,

When using the url, i see that all innputs work like they should. 
I think the problem is the port number, it doesn`t seem to match the input correctly.

Do you have an idea?

Correction, i missunderstood. 

It works, perfectly! Smile

It might be that array input order is not defined. Try this instead:
Code:
ports = {}

for _, p in ipairs(data.result.ports) do
  ports[ p.port ] = p.state
end

grp.checkwrite('1/1/1', ports['ext1.input1'])
grp.checkwrite('1/1/2', ports['ext1.input2'])

grp.checkwrite('1/1/2', ports['ext1.input2'])

it did work, i just didn`t change the port number.

it was on 1 and 2 and i didn`t change it. so when changing to 4 and 7 it worked perfectly.
the reason why it worked on 2 is becouse relay 1 is linked to ext.input 1 in the getface. 

[1] led_secured
[2] relay1
[3] output1
[4] input1
[5] ext1.relay1
[6] ext1.relay2
[7] ext1.input1
[8] ext1.input2

Thanks, for all the help! Smile

Hello dear Admin
If I want to do the job reverse, means I want to receive a command/trigger from the Getface IP, what is the http command from the zennio getface should look like?

You can use Remote services. See docs here (examples are at the bottom): https://openrb.com/docs/remote-new.htm
