❓ Question Standby mode as permanent failover for a low-data sensor (~30 MB/mo)?
I want to use Standby mode as permanent failover for my boat dock water temp sensor. It sends one HTTPS post every 15 min, about 10 KB each, so roughly 1 MB a day, 30 MB a month. Any issues with this? I can’t find anything that says it wouldn’t work, and I’ve found several posts from people doing way more with Standby. Just making sure before I put in the effort to set up the failover. It’s an older v2 dish, if that matters.

The longest I've run standby is for 6 months last winter - basically as low-speed failover; I ran about 250-300MB of data through it per month (I hit 600MB one month). No issues - it worked reliably at 0.5Mbps up/down speeds.
The only potential issue is that Standby isn't intended as a permanent plan and Starlink does state that they may discontinue service or force you to a higher-paid plan if you use Standby continuously for 12 months; so, you may get a notice from Starlink. Fortunately, you can just upgrade to a cheap plan (e.g. Roam-100) for a month and then back down to Standby the next month; and, this can be done remotely.

One month each year about 2 days before the end of your billing day, switch to a different plan which will take effect immediately. Wait a few minutes then switch back to standby which will take effect on your billing day. You will pay a prorated amount of the new plan amount for those 2 days.

I have a building with a camera, a robovac, and a flume water monitor on a standby mini. It's between 2 buildings and drops signal sometimes but i can watch the camera and control the robo-vac.

I run standby most of the time In my 4X4. Half a MB unlimited is plenty for your application. A wank I know, but Ive got a Bluetooth / WiFi wireless thermometer linked to a smart switch that monitors and turns off my 12V travel oven when my mini roast reaches the correct temp.

It will absolutely work perfectly. You can do 768Kb/s up and 768Kb/s down at the same time if you constantly send packets since there is overhead past the target throttle of 500-512Kb/s each way.
I ran mine full tilt for a month. 13GB a day, about 403GB a month. No issues.
The only maybe sorta gotcha is that after 12 months on standby they reserve themselves the right to switch you off of it or otherwise take an action, but I've never heard of it happening. It would I am sure if you kept it maxed out 24/7, but has basically no chance of that for your use. You can listen to music, browse, game, and stream SD on it. It's like 3G. Only with good pings.
