Is your umbrella a raspberry pi? I’m trying to do this too.
I have just set up DATUM from nostr:npub1qtvl2em0llpnnllffhat8zltugwwz97x79gfmxfz4qk52n6zpk3qq87dze on my nostr:npub1aghreq2dpz3h3799hrawev5gf5zc2kt4ch9ykhp9utt0jd3gdu2qtlmhct with BitcoinKnots and I am now mining with my Bitaxe and my own block template. Thanks, nostr:npub1qtvl2em0llpnnllffhat8zltugwwz97x79gfmxfz4qk52n6zpk3qq87dze and nostr:npub1ql2zzp3g6yndgz05js7wdc4qkr88wkyne5nw2cc7csrtzqs0yeesgwrxya.
