Adding Watchtower

Bitcoin and Lightning
1

I have myNode with Watchtower ON. I would like this node to watch my Umbrel. I found this guide how watchtowers works:

https://blog.bitmex.com/lightning-network-part-4-all-adopt-the-watchtower/

Is it safe to add this line into lnd.conf file:

wtclient.private-tower-uris=tower-public-key@ip-address:9911

Will it work? Questioning first, I don’t want broke my Umbrel. Would you recommend this setup? I’m not routing any payments, maybe it’s redundant? Both nodes are on UPS.

Thanks for reply.

The wtclient.private-tower-uris option has been deprecated as of v0.8.0-beta and will be removed in v0.9.0-beta. To setup watchtowers for the client, set wtclient.active and run lncli wtclient -h for more information.

I suggest to look into https://github.com/talaia-labs/python-teos

I’m looking to add a few watchtowers to my Umbrel node.

Is there any easy to follow guide on how to add a watchtower to monitor your Umbrel node?

Is it enough to activate the client by adding the following text at the end of lnd.conf

[Wtclient] (or [Watchtower]???)
wtclient.active=1

And then to add a tower use command:

lncli wtclient add pubkey@address
(Replace “pubkey@address” with the tower’s uri.)

Is that possible with the containers? Does that work with Tor? What happens with updates?

It’s already been posted before, just search around for “Watchtower guide”

This is for Umbrel 0.5.1
ssh -t umbrel@Your_local_umbrel_IP
sudo nano /home/umbrel/umbrel/app-data/lightning/data/lnd/lnd.conf

Insert at the bottom at lnd.conf
[wtclient]
wtclient.active=true

Then lnd restart
/home/umbrel/umbrel/scripts/app compose lightning restart lnd

Go to the Umbrel app-store and install LNDg
Go to the link Watchtower in LNDg and insert the Watchtower:
023bad37e5795654cecc69b43599da8bd5789ac633c098253f60494bde602b60bf@iiu4epqzm6cydqhezueenccjlyzrqeruntlzbx47mlmdgfwgtrll66qd.onion:9911

Thats all :slight_smile:

Install LNDg, click the ‘Towers’ link, there you can see your active Watchtower and stats.

when I open LNDg via tor
it opens up just this site with following

My Lnd Overview

An error has occured!

LNDg cannot reach the gRPC for LND. Make sure LND is running and/or your gRPC settings are correct.

Error Code: StatusCode.UNAVAILABLE

LNDg v1.3.0

I do that but it takes a long time and it doesn’t load, how to fix it?
