Trouble to connect Mosquitto MQTT

[lasse79]

Hi, just got my SH10RT and try to implemt it to the home assistant. Got SunGather running on eth port and getting out 39 registers. As soon i try to connect to the local Mosquitto MQTT Server SunGather quit with following faults: Traceback (most recent call last): File "./sungather.py", line 190, in <module> main() File "./sungather.py", line 158, in main export.publish(inverter) File "/root/SunGather/SunGather/exports/mqtt.py", line 123, in publish payload = json.dumps(inverter.inverter_config | inverter.client_config | inverter.latest_scrape).replace('"', '\"') TypeError: unsupported operand type(s) for |: 'dict' and 'dict' im running rasperryPi with python version 3.7.3

anybody lnow this issue or can support me? Thanks in andvance!

From the error message I would think that there's a problem with any of the 3 objects: inverter.inverter_config | inverter.client_config | inverter.latest_scrape. If you have the possibility to debug the code you could look into these objects. Or you just add this lines just before line 123.

logging.info(inverter.inverter_config)
logging.info(inverter.client_config)
logging.info(inverter.latest_scrape)

Once you have the output please post it here.

sorry my python skills are too bad to solve by my selfe, but anyway bayme it helps generall or other users as well

Can you try setting smart meter to true?

[michbeck100]

Another guess would be to update your python version to > 3.9

[michbeck100]

I think TypeError: unsupported operand type(s) for |: 'dict' and 'dict' means that your python version doesn't support merging multiple json objects using the | operand.

On buisness trip, will look into this next weekend, thanks for support

[lasse79]

sorry for the delay... on my side it was a combination on a wrong Firmware on the inverter and the not connected smart meter in the beginning. Right now it looks like it works and i can readout 39 registers! Thanks for the support

p.s. as well im running now python3.9 on a new installation

[pkerney]

I had same issue on Centos 8.5 until... as called out by @michbeck100 yum install python39 pip3.9 install --upgrade -r requirements.txt cd SunGather python3.9 sungather.py

Similarly had this issue - python 3.7 as part of openhabian. Managed to cludge the following workaround to merge the fields instead of using the | merge operand that wasn't supported until later versions.

exports/mqtt.py - line 123

#        payload = json.dumps(inverter.inverter_config | inverter.client_config | inverter.latest_scrape).replace('"', '\"')
        payload_merge = {}
        payload_merge = inverter.inverter_config
        payload_merge.update(inverter.client_config)
        payload_merge.update(inverter.latest_scrape)
        payload = json.dumps(payload_merge).replace('"', '\"')

Not fully tested, and I don't use HA - so I don't now if the merged output is identical to the original format, but it was sufficient to get the mqtt export enabled and functioning.

Thx.
