Getting empty response from inverter query command #13

Closed tannercollin closed 3 years ago

Hi, I am receiving an empty response when I query the ECU's inverters when running query_ecu(). Here's the output with some data I've added:

ecu query: APS1100160001END

Sometimes I get "Connection reset by peer":

I'm also running APSystems-ECU-proxy-for-cloudless-operation and it believes that it has internet connection. I had to adjust the script a bit to get it working:

offset = 32
date_time_obj = datetime.strptime(str(rec)[offset:offset+14], '%Y%m%d%H%M%S') + timedelta(minutes=-5)

It's sending messages like these every 3 seconds to ecu.apsema.com:

<< ECU: b'APS1300074A182AAA02162000051002021060317185900000000000000010US/PacificEND\n'

Any idea what's wrong? Thanks!

Update:

If I skip the initial query command and go straight to the inverter query it seems to work:

inverter data cmd: APS1100280002216200005100END

If I close and open the socket before each query, everything seems fine.
