I didn't even know you could connect eclair mobile to btcpay. Very cool.
With connect I mean open a channel with my BTCPay node, so all the payments I do go through my online node.
That's quite smart actually.
Where are you hosting btcpay? Do you have any costs to have that up?
I'm hosting it at time4VPS, it's about 30 EUR in 3 months. It's for 80 GB storage so only pruned blockchain which isn't ideal for obvious reasons.
It's the first I tried so probably not the best, but not that expensive.
