Counter output is always zero

[Hugoagogo]

I am attempting to reflash a Sonoff ZB-DS01 as a counter for purposes of logging a water meter.

I haven't used PTVO before so I am potentially screwing something up.

I have reverse engineered the following.

P06 - Reed switch with 100k pull up
P20 - Onboard Switch
P10 - Onboard LED

I am using the below configuration, it seems to flash ok using a CC debugger, and I can successfully pair with zigbee2mqtt, however looking in ZigBee 2mqtt I always see zero.

I am pretty confident the input works as I play around with configuring it as a switch input linked to a pretend output I can see it switching in zigbee2mqtt.

Any tips on what I am doing wrong or have I found a bug.

@Hugoagogo Sorry about the delay with my answer!

I've checked the counter, and it works as expected. The firmware sends the counter value with a periodic report or when you press a button on "P20". Please check that you've enabled periodic reports on the "Expert" tab.
