Sorry I should have explained further. Originally I upgraded to latest firmware via onion console. Once the upgrade completed any wireless connection to my omega2+ ceased to function. I tried to reset quite a few times holding reset button but things didn't improve. I thought maybe there was a problem with the newer firmware so I followed the firmware flashing from USB storage guide to downgrade to a randomly chosen firmware from the omega firmware repo. Once this completed my omega was alive again. I then connected through SSH and ran oupgrade. My omega is now on the latest firmware and working. Sorry if I have any terminology wrong.

I used an expansion dock. There is a guide in onion docs called firmware flashing from USB storage that I followed

I had the same trouble after upgrading. I ended up reflashing the omega via SD with a lower firmware and then upgrading again via putty.

Hi, I am looking for any information on getting the omega to read a flow metre. Basically just need to count pulses from a sensor. I have done a few projects out of the project book with the omega but haven't quite got my head around it all yet. I am hoping to get a flowmeter reading hourly that I can then SMS or tweet daily to recipient. I've read a few posts about interrupts and edge detection but haven't been able to set up docker to compile so was hoping for an easier way. Any pointers in the right direction would be appreciated. Thanks in advance
