Automatic export all logs and send by mail

[domotiqa]

Escaping of the "to" address was missing.
Here's a rewritten script with clearer structure. You only need to modify the to/settings/subject at the to top of the script. SSL settings do not matter anymore because newer SSL library automatically negotiates the highest supported SSL/TLS version between server/client.

Code:

to = 'to@example.com' settings = {   -- "from" field, only e-mail must be specified here   from = 'sender@example.com',   -- smtp username   user = 'sender@example.com',   -- smtp password   password = '12345678',   -- smtp server   server = 'smtp.gmail.com',   -- smtp server port   port = 465,   -- enable ssl, required for gmail smtp   secure = 'sslv23', } subject = 'CSV logs' logtime = os.time() - 60 * 60 -- last hour (3600 seconds) buffer = {'"date","address","name","value"'} query = [[   SELECT o.id, o.datatype, o.name, ol.datahex, ol.logtime, ol.eventtype   FROM objectlog ol   JOIN objects o ON ol.address=o.id   WHERE ol.logtime >= ?   ORDER BY ol.id DESC ]] for _, row in ipairs(db:getall(query, logtime)) do   if row.datatype and row.eventtype == 'write' then     data = grp.decodevalue(row.datahex, row.datatype)     logdate = os.date('%Y.%m.%d %H:%M:%S', row.logtime)     buffer[ #buffer + 1 ] = string.format('%q,%q,%q,%q',       logdate, knxlib.decodega(row.id), row.name, tostring(data))   end end csv = table.concat(buffer, '\r\n') smtp = require('socket.smtp') mime = require('mime') ltn12 = require('ltn12') function escape(v)   return '<' .. tostring(v) .. '>' end to = escape(to) msgt = {   headers = {     to = to,     ['content-type'] = 'text/csv',     ['content-disposition'] = 'attachment; filename="logs.csv"',     ['content-transfer-encoding'] = 'BASE64',     subject = subject,   },   body = ltn12.source.chain(     ltn12.source.string(csv),     ltn12.filter.chain(mime.encode('base64'), mime.wrap('base64'))   ) } settings.source = smtp.message(msgt) settings.from = escape(settings.from) settings.rcpt = { to } res, err = smtp.send(settings) log(res, err)

Hi, thanks for the script,

is there an easy way to separate in different csv file the log object and send them in one email?
