Does SmartStruxure Lite support e-mail servers that require authentication?

[Product_Support]

Issue

Unsure what options are available in the Lua smtp.send() function.

Product Line

EcoStruxure Building Expert

Environment

SmartStruxure Lite Multi-Purpose Manager (MPM)

Cause

The Lua smtp.send() function is not fully documented.

Resolution

The syntax of the smtp.send() function is:

smtp.send

{ from = string, rcpt = string or string-table, source = LTN12 source, [server = string,] [user = string,] [password = string,] [port = number,] [domain = string] }

From above you can see that the "from", "rcpt" and "source" fields are required. Whilst "server", "user", "password", "port" and "domain" fields are optional.

Example Lua code is:

--==============================================================================
-- SSL email notification script example
--==============================================================================

-- Define the input you want to monitor below
var("temperature", "ME.AI1") -- Room Temperature
limit = 78 -- define the threshold

now = scl.sysclock()
if (temperature > limit) then -- When temperature is above threshold
    if (sent == nil) -- Check if e-mail was already sent
    and ((last == nil) or (now - last > 15 * 60)) then -- Maximum every 15 minutes
        sent = true -- Only send e-mail once
        last = now -- Keep track of last time

    result, reason = smtp.send {
    user = "alerts@server.com",  -- Enter your existing SMTP username
    password = "test1234",  -- Enter your existing SMTP password
    from = "alerts@company.com",  -- Enter your existing Source address
    rcpt = {
            "user1@company.com",  -- First recipient
            "user2@company.com",  -- Second recipient
            "user3@company.com"  -- Third recipient
            },
    source = smtp.message( {
    headers = {
    from = "alerts@company.com",  -- Displayed source address
    to = "technicians@company.com",  -- Displayed recipients
    subject = "Temperature Alert"  -- E-mail title
                },
    body = "Current temperature is: " .. temperature .. " (above " .. limit .. ")" .. " [" .. os.date() .. "]"}),
    server = "server.com" – enter your SMTP server
                }

    if result ~= 1 then
        print(os.date(), "E-mail was NOT sent:", reason)
    else
        print(os.date(), "E-mail was successfully sent.")
    end
end
    else
    sent = nil -- Re-enable alerting on condition
end
