You can enter all the TOU rates into the Blink and it will track $ in the monthly stats...but don't do it using the Blink's touchscreen, or the web interface, use the BlinkNetwork.com site, it's much easier.
What monthly stats?
All I see on blinknetwork.com is from my "Dashboard" that my last charge was 1.0E-4 kwh, corresponding probably to the event of my unplugging the J1772. Usually it does tell me the kWh of my actual charging event, but not today. Also I can get tons of CO2 eliminated, barrels of oil and gallons of fuel saved, and dollars saved, as a line graph from when I got my car to today. They all look the same: uninteresting lines slanting upwards without enough scale or detail to be useful for anything. If I had a lot of spare time I could "mouse-over" each point and transcribe the data points day by day. Even with that laborious method I couldn't directly get kWh, though I could back it out from dollars saved if I knew what assumptions they were using for ICE MPG and gasoline cost. There is a link for "My Reports" which are always empty, nor does there appear to be any place to define reports.
The most useful stats seem to be from the Blink unit itself, which tells me the total kWh used so far this month, and last month.
I had expected that all this data would have been available in Carwings, and just as I can download the car's idea of how many kWh it has consumed day by day, I could also download how many kWh it received at each charging event. Ideally it would have both its idea of how many kWh went into the battery, and also the EVSE's idea of how many kWh left the J1772 plug. Ideally it would record some sort of station ID of the charging station. But at least it should record the start and end time of the charging session, and how many kWh the car saw.
That way, for example, you would be able to use your Carwings data to show your employer each month how many kWh you used to reimburse the money, without the employer having to buy an expensive EVSE with RFID authorization. Frankly I think the employer should, and probably would, skip the reimbursement after a few months of noticing that the amount is trivial and not worth tracking. But I also think it would often take real data for an employer to make that determination.
[Edit:] With so much useful and seemingly easy to collect data overlooked, I wonder how much information the EV Project will actually get from our cars and Blinks. I would have thought that both the EV Project and Nissan would have erred on the side of collecting more data than they need, and I'd be happy for them both to have it if it could in any way make the EV transition more successful.
