Only Some Sensors not reading

[hazardrr]

Hi There

i have HA installed on a Raspberry Pi 4. I purchased this USB to RS485 and its connected to RS485 on my Sunsynk 8KW Inverter https://www.robotics.org.za/index.php?route=product/product&product_id=5947

I installed the Add-on mid August and it worked fine even though i kept getting Timeout Errors in the log. A few days ago, i did maintenance on the inverter an shortened and re-crimped the CAT5 Cable running to the USB-RS485

Ever since then, i have been unable to get a reading on Total Grid import sensor. I re-install and redownloaded the addon (which will shows 0.14 by the way) and it still just timeouts with that sensor specifically.

I then added a few other sensors and the other sensors work fine except for Essential and non Essential Loads. So now 3 sensor readings keep timing out

Here is my log output:

I also tried adding TIMEOUT: 20 to the config file but it still does it in 10sec intervals

Your assistance would be highly appreciated

Thank you

just something i noticed as well, its actually not updating any values anymore. i reboot add-on then it pulls data only for that time. it doesn't seems to be updating on its own

i actually wonder if it also has anything to do with the Home Assistant 2020.9 update. i am currently on Home Assistant Core 2022.9.2

[hazardrr]

ok, i found the issue. For some reason it just stopped working after i re-routed the cable. Possibly interference. The cable is 36M long and even though it worked before, i suspect that closing it up in trunking caused some more interference because if I put my Home Assistant unit right by the inverter it works fine.

I would like to increase the timeout to see if that can help because of the distance of the cable but when i change timeout, its just still 10seconds. How can i change it to 15 or 20 seconds?

Hi Hazard, I will have to look into why the timeout is not being used.

I assume you use 3x wires (D+/D- and GND). the data lines MUST be on a twisted pair in the cable to reduce noise, but even then the interference might be too much. Another option might be a Shielded UTP cable. Then you ground one end of the shield to an external ground (You don't necessarily have to use metal STP connectors)

Hi Johann

Thanks, much appreciated, that would be great with the timeout function. I am using Cat5e yes and I and using 3 wires as per diagram yes. Strange thing is that it worked before. Now that I neatly put away the cables in the trunking and cut off excess wires it just stopped working completely. It reads on start up but then just times out so it does definitely seems like some interference (for about 10 meters its running in the same trunking as the solar DC cables). This is why i would like to try to increase the timeout to see if that will possibly work to accommodate for distance and interference.

If that doesn't work, i have another Raspberry Pi right by the inverter which I am using for reporting on my battery via Pylontech cable, I could maybe use that Raspberry Pi as a modbus gateway as a last resort

[kellerza]

@hazardrr the latest dev version tries to propagate this timeout for the usunsynk driver in the dev version of the addon, so might help!

btw, I use an old Raspberry Pi 1b running mbusd (no Hass io) as a gateway with a wave USB adaptor

If I would start today I would likely choose this Wave RS485 to Ethernet unit

This latest published version today broke my add-on. It cannot start up. Not infront of a pc to debug yet.

@jabezz can you try updating again, it seems connection_timeout is not supported by serial drivers. I only have a TCP test system

[jabezz]

Perfect. Working again. Much appreciated.
