KNX connection statuss and device check

[AlexLV]

Hi,

at Russian FB page found some interesting scripts, I think can be useful, not seen here..

1. KNX connection status:

Code:

if not client then  
   require('genohm-scada.eibdgm')  

   function statushandler(status)    
       if status == 0x00 then      
           grp.write('32/2/1', true)    
           elseif status == 0xFF then      
           grp.write('32/2/1', false)    
       end  
   end  
   client = eibdgm:new()  
   client:sethandler('status', statushandler)
end

client:step()

2. KNX device check, if any lost, automatically message can be sent (with russian comments, I added english translation):

Code:

-- Таблица адресов, которые нужно проверять на доступность на шине
-- Table of addresses which should be checked at KNX line
knx_addrs = {'1.1.2','1.1.4','1.1.5','1.1.6','1.1.7','1.1.8','1.1.9','1.1.10','1.1.11','1.1.12','1.1.13','1.1.14','1.1.15'}
-- Таблица подключенных устройств
-- Table of connected devices
knx_conn = {}
-- Таблица отключенных устройств
-- Table of disconnected devices
knx_disc = {}

-- Проверка доступности устройств на шине KNX
-- Checking devices are alive
for index, value in ipairs(knx_addrs) do
if knxlib.ping(value) then
table.insert(knx_conn, value)
else
table.insert(knx_disc, value)
end
end

-- Перевод таблицы в строку
-- Table translation to string
conn_str = table.concat(knx_conn, ', ')
disc_str = table.concat(knx_disc, ', ')

-- Вывод таблиц и строк в лог для просмотра при отладке.
-- Logging of tables and strings for debugging
--log(#knx_conn, #knx_disc)
--log(conn_str, disc_str)

-- отправляем письмо со списком недоступных устройств, если такие найдены
-- sending message with disconnected devices if any
if (#knx_disc > 0) then
log(disc_str)
--mail('example@email.com', 'Проверка устройств KNX', 'Отключены следующие устройства: ' .. disc_str)
-- translation of russian text above string: "KNX device checking" "These devices are disconnected:"
end

But please check second script, approx. every day I see in my log that some devices are offline, but they are different.. Looks a little strange for me.. But all works. May be something should be improved in script.

Hi
I would add some delay in the second script in for loop.  During ping quite a lot of telegrams is sent so it is better to do it one by one slowly.
Thanks for sharing.
