Replacement tuner for mecool ki pro?

I received for free a couple of Zgemma H2S (Enigma) boxes that had previously been used for a defunct dodgy IPTV service.
I put a new version of Enigma on them and installed a plugin to provide Sat>IP from the tuners.
I have CE running with tvheadend server on an old ARM device (S905W) which distributes all channels throughout the home.
I had never even used Enigma previously and it took me a couple of days to understand how it all worked.
I split my cable from a Unicable LNB and the Zgemma devices worked well.
If such devices are being discarded in your locality, as they are in mine, then I think it might be worth spending a little time on one to see if you can use it.
I bought another used Zgemma with DVB-T2 tuners as my HDHomerun device crapped out, and now that Zgemma is my sole source of DVB-T tuners … previously had TBS in PC, then several HDHomerun devices which were not reliable, and now the Zgemma.
Yes it is an extra device, but as I do not use it for display out, it is put away in a cabinet and connected to the LAN.
I mostly use a Digibit R1 for DVB-S/2 but have on occasion also use the Zgemmas when required.
You might be surprised at what can be achieved.
