Should be pretty straightforward on Umbrel. They will need to switch to Knots instead of Bitcoin Core, but other than that, you just tell DATUM to never get reward splits from OCEAN, give it a bitcoin address to send to, and plug the stratum address into your BitAxe's dashboard, and you are solo-mining with no pool at all.

Did MyNode have DATUM?
Not sure if anyone has packaged it for MyNode. nostr:npub1wnlu28xrq9gv77dkevck6ws4euej4v568rlvn66gf2c428tdrptqq3n3wr would probably know, though.
Just checked their telegram group, doesn't look like it. MyNode is still being updated it seems, though perhaps no new stuff like DATUM. Can't really blame them though. They've been at it a long time and it would be largely a thankless task.
In the scheme of things, DATUM is quite new. Only been around since what, September of last year? Still a baby.
Usually it takes someone who is using a node implementation, who has some dev skill, and who wants to use the application himself to package an app for that platform. It's usually not the devs behind the node implementation itself who take it on.
The less popular the node implementation, the less likely the person with both the skill and the interest in doing the work exists.
Just upgrade mynode and datum will appear on the store
Thanks I will tell them try that since I think mining pools charge a fee.
Where you find the stratum address?
