"your wallet uses less efficient method of querying electrs" - What method to use if not blockchain.scripthash.get_balance?

[MvdS74]

I have Electrs running and it is working fine, I am playing around with some Python code and when calling blockchain.scripthash.get_balance or blockchain.scripthash.listunspent I see "your wallet uses less efficient method of querying electrs, consider contacting the developer of your wallet. Reason: blockchain.scripthash.get_balance called for unsubscribed scripthash" appearing in the logs.

Is there a more efficient way of querying electrs and if so, what method should I use?

You need to subscribe to the scripthash first and then query the balance. Note that this makes most sense when you use it for long-term monitoring. IIUC a one-off script will be equally inefficient in both cases.

So I just have to accept the messages in my log file in case I am not interested in keeping track of those addresses?

[Kixunil]

Yes. I guess we should have a config option to suppress that specific warning.

Ok, thanks for your answer
