Under Settings > Troubleshoot you can get logs which include the Pi4 temperature. If you’re on the same WiFi with your phone you can access to it the same way (umbrel.local), otherwise use your onion link.
If you want to look at your node from your smartphone, you have two options.
1: Use any browser and umbrel.local link or IP adres for node, but the condition is to be connected to the same network as the node.
2: To connect remotely from another network, you need a Tor browser, you enter the .onion address you find in your node settings.
I just installed Tor Browser on my cell phone since no other web browser on Android seems to work
I am getting an “unable to connect…try again” message when I type umbrel.local maybe because I am still downloading the bitcoin core, which has been running for a day and a half now. It is at 66% now.
It is running slow because although I installed heatsinks is it running over 80 degrees. I ordered a "Raspberry Pi 4 Metal Case with Fan,Raspberry Pi 4B Case with Raspberry Pi Low-Profile CPU Cooler,Raspberry Pi Horizontal ICE Tower Cooler (Silver), which should arrive tomorrow sometime. I assume the speed is due to the heat.
There’s a nice app for iPhone called ServerCat (not sure if it have an Android version tho). It connects via SSH and gives you a lot of info, including temperature of course. You can even open a shell. It’s really handy.
It’s a good point. I still haven’t fund my node neither have lightning channels open. So not much risk here. Besides the node is only reachable in the local network. The app should have a back door to gain access, which is possible, even in the Apple App Store. I agree that one should be careful.
It’s probably best not to use it in the case of node.
Still, can change credentials since its via password.
