memoryview: a bytes-like object is required, not 'str' about weewx-zabbix

[RandomReaper]

Thank you for the report,

I currently quite overbooked, but if you could try to replace the line 90 from:
sender_stdout = p.communicate(input=s)[0]
to
sender_stdout = p.communicate(input=s.encode())[0]

Hello.
I changed lines 89 and 91. It seems to work with: universal_newlines=True and text = True

        p = Popen(c, universal_newlines=True ,stdout=PIPE, stdin=PIPE, stderr=STDOUT)
        ...
        loginf(self.zabbix_sender + " result: " +sender_stdout)

I get this out output but it seems to be other problem. I test zabbix-sender manually

Dec 15 11:59:56 pi2weewx /weewxd[26457]: zabbix: /usr/bin/zabbix_sender result: Response from "XXX.XXX.XXX.XXX:10051": "processed: 0; failed: 32; total: 32; seconds spent: 0.000570"
                                         sent: 32; skipped: 0; total: 32

If I remember correctly, processed 0 is because the item does not exists in zabbix.

You just masked the line I was asking you to change? I don't even know what you tested...

[HoracioDos]

Hello:
I tested what I answered before. I inserted universal_newlines=True in popen() in line 89, It also works with text= True and I removed decode() in line 91. I will test your change later.

        p = Popen(c, universal_newlines=True ,stdout=PIPE, stdin=PIPE, stderr=STDOUT)
        ...
        loginf(self.zabbix_sender + " result: " +sender_stdout)

Zabbix items were already created. I'll build a template if I have the time. I know why zabbix_sender is not working. I use PSK to cypher agent to server communication. I will add the config file that it is needed
-c /etc/zabbix/zabbix_agentd.conf

to

Your solution works fine.
I added the config file parameter. It's working now with PSK.
I'm trying to figure out why zabbix_sender runs 3 times each time.
What's the units for send_internal?
Thanks!

Fixed for python3 in 7ca4c9f.

[RandomReaper]

I think, but you should verify, the units are the same as the internal zabbix units (see http://weewx.com/docs/customizing.htm#Changing_the_unit_system).

Hello!
I think Send_interval parameter is in seconds. As far as I understand, time difference result in your code (line 77) is in seconds. Is that correct?
Thanks!

Send_Interval = 290 seconds works fine if I want to send values just once in the packet loop. This way matches with the archive interval.
