Hi

In the last few days I've faced a bus lock issue in my RA*....twice...

All the suddenly, my RA* stopped working, and turning it off and on seems to have no effect. My lights port is locked On, even if it is showing as Off both on Uapp or in the RA* screen.

My concern is if any other port is turned On, let´s say "Water In" port for instance. I may be looking for a overflow in the near future...

Anyway.. started unpluging the expansions one by one (the data cable, not the power cable) and when I unpluged my new ORP expansion, RA* backed active.

It was 01:30 am by then.. hahahaha

Never had this kind of problem before. What can I do?

Rafa

Yeah I was paranoid of having a buslock happening during dosing or topping off which would be disastrous. I ended up using some time delay relays for the dosing pumps and ato that are connected to the RA* but will shut off after a set time even if there is a buslock. For the non critical devices and buslock itself I set an alarm so I can reset the RA* remotely, which normally gets everything working again. Maybe there's a better solution but this will help me sleep at night.

Tngo tks for sharing.
In my case, rebooting had no effect. Let's wait for more ideas. If It happens when I am not home, I don't know what to do...

Check the USB cable. I had some bus lock problems I pinned down to my water level expansion module. I discovered slightly moving the usb cable connector where it plugged into my expansion hub would create or fix the bus lock. I changed cables and so far, no more bus locks not even with wiggling the usb cable connector.

I just patched the libraries.
On RA*, I implemented a chip that powers the bus independent of system power.
So, in the case of bus lock, RA* will turn off the expansion bus and tries to re-initialize it and power it back on.
Can you upload your code again using the webwizard and let me know if things get better?

I cant use the webwizard. I customized the library, modifying the waterlevel gain. Can I download the Dev library and use It?

BTW.. any chance implementing a custom waterlevel parameter to pass the gain? Would be awesome to use the webwizard.

That's a pretty cool feature Roberto. Thanks for implementing it in advance.
