http/https poller

[Jumper3126]

Got it running
Perhaps not the cleanest way, but it works and that is the main goal

Wrote a bash file, based on this onehttp://www.domoticz.com/forum/viewtopic ... ase#p56105.
I have 14 panels, you'll have to adjust the script for the amount of panels, the ip adress of your enphase gateway and the installer password of your system (see https://thecomputerperson.wordpress.com ... r-toolkit/).

Run the script every 5 minutes using crontab

Code: Select all

#!/bin/bash
# bash script to read production per panel from Enphase gateway
# V1.0 15/09/2018
# Based on script by Koen Vanduffel

Hello Jumper,

i am trying to get your nice script to work on my domoticz but i run into some problems.
could you help me out on how to edit the script?

envoy.sh.txt

(4.17 KiB) Downloaded 155 times

i got some faults in the log about Illegal characters found in URL curl, al to do with the last lines , if i remove some lines i get less faults.

fault log.txt

(1.84 KiB) Downloaded 84 times

at this moment i see from 12 panels values in the log ( i have 13) but no readings in the virtual sensors.

i hope you can point me in the right direction , i am new to this scrips.

greetings marco

Hi Guys

I rewrote the previous script into a lua script. So everyone can use it in the events of domoticz. It is lua time based script.

Fill in your ipadress of the envoy device.
Fill in passwd for installer (see previous reply)
Fill in the serialnumber of the microconverters

the code as comments could be used as debug info.

Code: Select all

interval = 1
local m = os.date('%M')

if (m % interval == 0) then

json = (loadfile "/home/root/domoticz/scripts/lua/JSON.lua")()
local config=assert(io.popen('curl --anyauth --user installer:****** http://ipadress/api/v1/production/inverters')) -- json data off all micoroconverters
local Stringjson = config:read('*all')
config:close()
local jsonData = json:decode(Stringjson)

commandArray = {}


tc = #jsonData
for i = 1, tc do

	if ( jsonData[i].serialNumber == "serialnumberpanelx" ) then
        print("panel 1")
--	    print(jsonData[i].serialNumber) 
--	    print(jsonData[i].lastReportWatts)
        panel1=jsonData[i].lastReportWatts
       
		
	elseif (jsonData[i].serialNumber == "serialnumberpanelx" ) then
		print("panel 2")
--        print(jsonData[i].serialNumber) 
--	   print(jsonData[i].lastReportWatts)
       panel2=jsonData[i].lastReportWatts

-- repeat as many panels you have 	   
	   
	end 
end

  commandArray[#commandArray+1] = {['UpdateDevice'] = 'IDXdummypanel1|1|'..panel1}
  commandArray[#commandArray+1] = {['UpdateDevice'] = 'IDXdummypanel2|1|'..panel2}

end
return commandArray

Hello lightmanster,

Great tht you spend time on this thing , i realy like to get it working.

but i run it to some problems withe the script

i get a message at line 6 (see pic)

6 json = (loadfile "/home/root/domoticz/scripts/lua/JSON.lua")() if i remove the last () then the next fault is move to line 10
10 local jsonData = json:decode(Stringjson) ( do not know how to troubleshoot further

Envoy2.txt

my lua script, without pw

(4.23 KiB) Downloaded 106 times

wat i did so far :
setup/harware ,create 1 dummy (idx10) and create 13 virtual sensors under it (idx 39-51) the custom type.
put lua script in events to let it run by domoticz (with serial numbers idx and pw)
also try to run it from home/pi/domoticz/scrips/lua

i hope you can help me out , i am new to working with these scripts , can not find out wat i am doing wrong.

[berrevoets]

just found one fault in my script, i wrote the serial numbers wrong in it without the first char.

still i get the same fault

2019-02-03 13:46:07.780 Error: EventSystem: in envoy 1paneel: [string "interval = 1..."]:6: attempt to call a nil value

i did login on the envoy, checked the serial numbers and the string my string lookslike:

]
{
"serialNumber": "121816023245",
"lastReportDate": 1549197357,
"lastReportWatts": 115,
"maxReportWatts": 164
},
{
next panel....


do i have to fill in a idx ? how wil it look like for one panel with the IDX =39 and the name is dummypanel1 ?

Is it possible to run a php script instead of a lua?

I really suck when it comes to lua. I do prefer PHP at all times.
At the command field I do want to run a PHP script running on my HTTP server...

Well I guess not.
Feel kind of stupid to call a lua script and then php script from inside lua.

Well well. This should be changed in further versions of Domoticz.

Suggestion: Have a look at Pass2php and have as many php as you want at your fingertips.

[Minglarn]

Thanks for the tip.. I'll do that.

Hi,

This thread suppose to be a discussion on how to use the http/https poller.
However it is more focussed on how to get the power production of each Enphase solar panel inverter in Domoticz. All kind of scripts are used, bash, lua, etc. In my opinion the best would be, that it is natively supported by Domoticz.
Therefore I made a request.
See: https://www.domoticz.com/forum/viewtopi ... 31&t=29170.

However I don't get any reaction from the developpers so far.

If it is only about, how to get the power production, max power and the inverter status in Domoticz, I can publish my Node Red flow(s) with some explanation.

Regards

Hi,

As said, the topic on how to extract the individual Power production of Enphase micro inverters with Node Red and MQTT has nothing to do with the http/https poller. Instead of continuing here I created a new thread, specific for this topic.

See: https://www.domoticz.com/forum/viewtopi ... 14&t=29331.
