Will Bitcoin Core only show balances for UTXOs created after you`importdescriptors`? Or am I screwing this up somehow?
This will depend on the value of "timestamp" in 'importdescriptors'.
In the example in the OP, he used "1647182091" which is the epoch date of "Sunday, March 13, 2022" so Bitcoin Core will only rescan blocks past that time.
If you want to rescan from the genesis block, set it to "0"; if you do not wish to rescan, set it to "now".

Thank you for sharing this! This is a better solution than my findings.

I have done this and it shows success in the console output for Bitcoin Core 0.22

However, I do not see the balance I would expect.

Will Bitcoin Core only show balances for UTXOs created after you`importdescriptors`? Or am I screwing this up somehow?

Edit: It would seem like it will only see UTXOs that happen after I did the import. This could be worth mentioning. To test, I just reused an address (I DON'T DO IT EVERYTIME, OK!) and sent myself a small amount. I now see this TX show up in Bitcoin Core with the watch-only wallet setup as per this guide.

Edit#2: Forgot about `rescanblockchain`. Used that and it worked. Don't forget to specify a blockheight to start at unless your wallet is super old. (I rescanned starting just before my first TXid block height)

...it will run even at below 200v, but then your miners will RIP if that happens too often.

Is there a place where this is elaborated on? How many cycles of <200V would cause the miner to RIP?
I'm asking because I'm interested in how many cycles a standard S19 PSU could be at 0V before RIP.
Short answer: not many and for any 1-event not for very long. If for some reason the miner/PSU continues to operate you risk serious damage to the PSU. Good part is that the PSU *should* shut down before damage occurs. Bad part is that given your concern I take it you have a very low/unstable power source - big problem.

If the main issue is just a line that normally holds around 208VAC (preferably higher) and occasionally may drop below 200v you may be ok, just expect the miners to hopefully restart once the powerline is back into a usable range. If dropping to a low line voltage is a fairly common thing you need to address that.

Thanks for the reply.

It sounds like some sort of intermediary device would be needed to help regulate the voltage so an immediate drop wouldn't occur. I've considered a standard UPS system but am trying to avoid excess equipment where I can.

In the random off chance that someone sees this and is in the Winchester, VA area. Feel free to message me about details.

For anyone else coming across this post, feel free to post suggestions/ideas for this meetup.

I am starting a local meetup group focused on educating folks about bitcoin. Ideally, I can get small business owners to attend and learn how to adopt bitcoin as an asset, so they start taking payments. Smiley

Where: Winchester, VA (DM me for details)
When: May 2nd, 7pm
What: Shenandoah Bitcoin Meetup
