What parts do I need to make a Jet Black DynoMeter functional again?

[bygonebiker]

Dear Sirs and Hers,

It's been at least a couple years since I logged in and now I can't use my old account, in that time many kilos have been added.

I have a JB DynoMeter which I bought 2nd hand off ebay about 3/4 years ago which I was hoping to use to start getting back into cycling.

It's still in good condition but the digital display panel and cadence sensor no longer function.

Is there any way of buying an aftermarket cadence sensor and display panel / bluetooth / app so I can start my exercising again?

If I had to buy another trainer it'd be a JetBlack Z1 Fluid (350).

What are my options?

Any help would be appreciated.
