Need help in scanning Digital TV spectrum
A few months ago my cable internet went down and I found this youtube video showing how to diagnose cable TV using an rtlsdr and the Spektrum spectrum analyzer. My internet came back on before I could take any good measurements but it seems like what you are looking to do.

Does Spektrum work with HackRF One?
I'm talking about this software: https://github.com/pavels/spektrum

Coming back to RTL SDR
SDRAngel may be worth looking into. Also not really a SDRSharp kind of app but recently I've been using Spektrum a lot to monitor bands that are wider than the 2.4MHz bandwidth of the rtl devices. I haven't tried SDR++ yet but its feature list looks very nice.

Hackrf one as swr meter/antenna analyzer
The highest frequency a RTL2832U-based SDR can reach is apparently 2.2GHz. (https://osmocom.org/projects/rtl-sdr/wiki) But if you are willing to do some programming, take a look at https://github.com/pavels/spektrum. Maybe you can port it to a different SDR.

Noob question, how to locate frequency of a device?
Spectrum analyzer software like Spektrum (https://github.com/pavels/spektrum) can do a large bandwidth sweep and help narrow down the device frequency.

Does Spektrum work with HackRF One?
No. QSpectrumAnalyzer has some feature overlap and can use HackRF with hackrf_sweep or soapy_power.

I don't know if my HackRF is broken but anything in HF range it gets jumpy and I can't make out any specific frequency. I got the Portapack H2 on top if it makes any difference. on win10 and Mac I got the same problem, also with different antennas.
Here is some good news though: There is a way work around this sampling rate restriction. Since you don't really care about the actual data, and you're more trying to just visualize the traffic, there is a special mode that HackRF's support called "sweep mode." In sweep mode, the HackRF will rapidly re-tune the antenna across a huge swath of the spectrum to give you a birds-eye-view of a much larger frequency range. Unfortunately, CubicSDR (and most other SDR software) does not support the HackRF sweep mode natively, so you'll need to use another tool, such as "qspectrumanalyzer" which supports this view. Qspectrumanalyzer is a python application that can interface with a HackRF and work in sweep mode, giving you a view 1 MHz - 6 GHz almost once per second. Granted, you'll want to tweak this down to just the 2.4 GHz range and play with the setting to get the view just right, but it should be possible to see what you're trying to see.

How do you find a radio controller's frequency to use the hackRF?
qspectrumanalyzer (https://github.com/xmikos/qspectrumanalyzer) will do this.

Hackrf cannot capture wifi signals ?
QSpectrumAnalyzer is an example of a tool that can make use of this.
