Good morning all

Just Q ?

My system in overal works OK but in 7-10 days WiFi dongle decide to drop from my home WiFi network and only way how to goes back online is disconnect dongle from inverter USB and connect back - already tried change Wi-Fi 2.4 chanel.

Right now I am away for 10 days and this happens yesterfay any ideas if this can be sorted remotely?

In future I been thinking of time relay and reset 5V line for USB every 24 hour.

BTW router is set for 80W permanent to cover all my house needs when Iam out than no drama ;)

Maybe your router (DHCP) kick the WIFI Stick - did you connect it to a Guest network? usually routers are configured to 'forget' non active clients after xx days (aka. DHCP Lease)
 
There is good point thx I will try look for when I return home and set static ip by mac address

But why other devices as NEST thermostat or Google speakers works OK
 
I doubt the router is dropping due to inactivity, tbh. A lot of routers will set a huge day range for the lease (like weeks), and if the device is still present when the lease is up, it gives the ip back to that device. Only time IPs will rotate is if there are more devices than addresses available. Not likely on most home installations.

I'm going to guess it's more something to do with the client.

Have you tried doing a firmware update? How often does this happen? When it does drop, is it the same number of days or is it more random.

Before updating the firmware, I would record the intervals and length of each reset period. I know that's a long time overall because it's days, but it might help the debugging process.
You can contact SOYO about the problem and it's possible it could be a defective unit

Another thing that could cause it to disconnect like that is a failing capacitor and the power supply (internal to the dongle) is becoming unstable and locking up the IC.
Possible it could be overheating and causing the issue as well, as the IC could overheat and lock up. (this one you could test by applying some heat to the dongle (hair dryer perhaps) and see if it drops faster)
 
It just triggered me about the DHCP because he wrote 7-10 days... I agree that it's probably more because of a poor programmed microcontroller - could be an overflow / crash and no reboot/reconnect - I also bought one of these inverters with the wifi dongle and I ordered a second wifi dongle too for testing. I was really disappointed with the registration process and so on. I even had to borrow a phone from my work because the app. only support a specific android version... I ended up taking the display from another inverter and use the software Klaus Li made. It's a pity that the ruined this good inverter with that wifi garbage stick...
 
Just simple Q?
Had anyone experience same behaviour of wifi dongle?

I have the Sun GTIL2 1000 and initially had a couple of the old dongles.

I also had a heck of a time getting them to work and I also did a reserved DHCP by mac address and that stabilized it a bunch.
I did get a bit tired of having my information go to china for me to view, so with some code I found that I adapted to my needs
I now gather this data locally to influx and grafana with an esp32. Not sure how the Soyo GTIL would do this but I'm sure it could be done.

Just update - I contacted my Internet provider virgin UK and they been able restart router remotelly but SOYO inverter still offline 🙃

It does invertor remember last settings and has been set to 80W constant power to cover all my house idle.
 
That's a good sign, I'm almost sure that the settings is saved to the stick, so it must be the wifi part. When I installed the display from another inverter, all the old settings was still there - that's why I think the settings is either saved on the stick or display - not on the inverter motherboard.
 
Just came home and inverter working OK alone and produce cca 70W even without USB WiFi dongle

But Blue LED constantly ON and no connectivity 2nd Blue LED at bottom and looks like dongle forgot WiFi

Going try to configure WiFi again

#edit after painfull WiFi reconfig all works again ;)
now MAC Adress allocated and and Lease time is 0

Just wondering now my IP is pernament how I can find web access to dongle?
Did anyone know how to sniff WiFi coms on certain IP 192.168.0.xx

? Other Q I have what if one day Chinese server at http://web.soyo-dg.com will stop working how I will be able adjust inverter... 🤔

That's the main reason I completely avoided using anything external to my home network. Hence RS485 comm's only. Been active for months on end without any issues (5 inverters - 4 controlled 1 fixed). Read my thread as you are making life hard for yourself.

The demand values are updated every 500ms or 1 second depending on the inverter and setup so you should have a constant stream of data going to China and comming back (after they store your usage data). DHCP will never timeout an active link like this, static IP will only clarify it's not your network. Use WireShark if you want to look at the data stream (which will likely be encrypted fom the external traffic to China).

Your whole setup as it is will never be reliable because you have a multi thousand mile loop that you have zero control over.

Either accept the uncontrolled environment (and a stuck inverter at 700W that flattens the battery) or change it.

Yesterday stupid WIFI dongle drop again and inverter OFF-line
Try reconnect but not success Blue LED not works at bottom of ESP8266 dead

thanks to advise of ;)

hopefully that'll keep it up. It's difficult to diagnose a problem like that when it's just so erratic when it happens.

quite silent on the western front for roughly a year so I want to ask if your system has been stable now for the past 12 months ?
Thanks
