No MQTT messages? - Githubissues

WPluim commented 6 years ago

Hi Arjen, Sorry to be back, but there we go. I can see the GoodWeUSBLogger making contact with the MQTT-broker. That is when I subribe to the item '$SYS/broker/clients/total'. The number goes up from 1 to 2 after I give the command (sudo python ./GoodWeUSBLogger.py start) on the Pi connected to the inverter (in the attic). The Pi that I want to get reading the data is near the P1-meter (downstairs). No matter what I try, like subscribing to:

power
power/
power/+
power/# I never get any messages with data, nor serial, nor online/offline. Do you have a clue for me what to do? Thanks in advance, Wilfried

No problem.

MQTT connection works. You confirmed that. Great. Next thing is if you are listening to the correct MQTT topics. The topics are:

//data //online Looking at your question, you also checked that one. Last issue that remains is that the GoodWe USB logger application did not complete the device Registration and Confirmation cycle. The device needs to be confirmed before the GoodWeUSBLogger application starts sending messages to MQTT. Can you confirm that the Solar Inverter has been completely registered? Best option to verify this is to set the log-level to DEBUG in the GoodWeUSBLogger config and observe the log-file for the correct sequence of events. Please provide any logging you get from your solar inverter after setting the log-level to DEBUG. I'm happy to help you crack this nut.

Excellent! I set it to DEBUG earlier this afternoon. I could not learn much from the output. It says: 2018-04-09 15:56:43,997 run(56) - INFO: Connected to MQTT 192.168.0.101 2018-04-09 15:56:44,001 resetWait(215) - DEBUG: Wait 0 minutes before next device poll 2018-04-09 15:56:44,050 resetUSBDevice(231) - DEBUG: Found GoodWe Inverter at /dev/hidraw0 2018-04-09 15:56:44,113 openDevice(272) - DEBUG: Connected to /dev/hidraw0 2018-04-09 15:56:44,215 sendData(325) - DEBUG: Sending data to inverter: 0xcc 0x99 0x9 0xaa 0x55 0x80 0xb 0x0 0x2 0x0 0x1 0x8c 2018-04-09 15:56:45,318 sendDiscovery(605) - DEBUG: Sending discovery 2018-04-09 15:56:45,319 sendData(325) - DEBUG: Sending data to inverter: 0xcc 0x99 0x9 0xaa 0x55 0x80 0x7f 0x0 0x0 0x0 0x1 0xfe 2018-04-09 15:56:54,257 handle(655) - DEBUG: State machine time-out.

The Solar inverter is not sending any data at all. It issues the Discovery command by sending the bytes 0xcc 0x99 0x9 0xaa 0x55 0x80 0x7f 0x0 0x0 0x0 0x1 0xfe. A confirmation should be replied by the inverter. The state machine keeps trying to Discover your device on the USB port. The device itself is not reporting anything back. How long have you kept it running in this state? What type of inverter do you have? I know that some GoodWe inverters only work using USB when the WiFi module has been disconnected.

Ik ran it two times for about three minutes. Tomorrow I could do that for one hour, several times if necessary. The Inverter is the Gw-4000SS. Indeed it is sending on the WiFi. I hoped I could have it (the data) both ways. That seems to be difficult though. I choose your GoodWeUSBLogger solution, because I did not want to open the Inverter at all. Quarantee-issues etc.

The fact that there is no data coming from the device itself could be related to the WiFi module. You could also try to verify if it is supposed to be working by connecting a laptop (Windows) to the inverter and run the EzExplorer application of GoodWe. If you have trouble finding that tool, please drop me a private message with your mail address and i will send it to you by WeTransfer.

Well, my finding this afternoon are:

I ran the logger for about 2 hours and nothing new came from that. The messages were repetetivly the same.
I installed the EzExplorer on the laptop and that got no connection either. So no luck with the USB. And than for the RS485-port: little chance there. There should be two (see the manual at http://www.westlandsolar.nl/solar/goodwe-gw4000-ss), but two years ago the old WiFi-module died and the guys from Utrecht/Zevenwouden (http://www.goodwe-power.com/CustomerService/Index) installed a new one. So there is one antenne now and no RS485-ports are in sight. Before I decide to open up the case I will contact the customer service center. If you like I can send you pictures of the inverter, just let me know. And of course I will keep you up-to-date if I make any progress. Thanks again for your help! Wilfried

Seems the whole USB connectivity is disabled/broken on your inverter. Sorry, but at that point I'm unable to assist.

Hi! Bij GoodWe kwam ik ook niet meer verder. Dus maar Google geraadpleegd. Zeer interessant: www.youless.nlVoor € 100 P1 en panelen monitoren met slechts één luciferdoosje! Op 11 apr. 2018 7:46 p.m. schreef Arjen notifications@github.com:Closed #7.
