The status of electrum server, for the moment can be seen only through SSH into node and check the logs. But I see that you are not “prepared” to do that. So you better wait until new releases of Umbrel will show in the dashboard a nice graph of status of all apps and services of the node.
You should start reading the guides we were preparing for new users:
“where is the private key for that? Is it the passphrase of 24 words that we wrote down when creating the umbrel setup?”
Yes, all you need to keep safe is that 24 words seed and a backup of your channels
“What is Electrum Server?”
- The server indexes UTXOs by address
- The server requires bitcoind, leveldb and plyvel
- The server code is open source. Anyone can run a server, removing single points of failure concerns.
- The server knows which set of Bitcoin addresses belong to the same wallet, which might raise concerns about anonymity. However, it should be possible to write clients capable of using several servers.
