You mean fire out data as fast as possible and take care of processing on the server? I'd be okay with that if necessary, but so far I haven't found one that seems to even measure the power consumption fast enough. They all average over some time frame between a few seconds and even minutes. This is of course fine for regular home appliances, but not fast enough for the problem I'm trying to solve.
Sadly, manual reflash is sort of a non-starter for my specific situation, but I have found devices that ship with Tasmota and ESPHome preflashed. I ordered a few to test.
To be honest, my question is not actually related to HA. I asked it here because it is by far the largest topic adjacent community on Lemmy and I was hoping to increase my chances of getting a good answer because all the home automation pros surely hang out here. You busted my con!
It's actually not so much the fast interval that I'm looking for, but fast response to changes in power consumption. In fact, I'd prefer not to be flooded by multiple messages per second but to only receive them on significant change (where "significant" would have to be configurable.)
The Shelly AZ I have been thoroughly testing sends out MQTT messages when power consumption changes, but has a delay between 1.5 and 2.5s, sometimes up to 5s. If this were either faster or at least consistently delayed by the same time, I could use it.
Reading up on Tasmota I've seen the PowerDelta configuration value which I think is what I am looking for...
I have no experience with esphome. This list has many of the "usual suspects" (Nous A1T which I have yet to test, Shelly Plug S) but how will this solve my problem?
I see that there are a few like this one that come with esphome preinstalled (a requirement for me, I can't use smart plugs I individually have to reflash.) In the device's config file I see a variable sensor_update_interval: 10s. Is that what you mean?
Using it to backup from a QNAP. Works very well and hassle-free. I'm using the QNAP backup app, but would be just as easy with any other tool. Just make sure to encrypt the backups.
He's learning to shift and pedal right now and basically stay on the bike for a little longer, and you're suggesting he spend another few hundred at the very least on a power meter? That's bad and gate keepy advice in my opinion. He does not need a power meter; not for a while, if ever.
In terms of pedaling, it doesn't matter. The same ratio between teeth in the front divided by teeth in the back will feel exactly the same. The only rule here is that you are aiming to keep the chain in a somewhat straight line. Supposing you have two chainrings in the front: Never go small-small or large-large, as that would put strain on the components. For a 2x11, for example, usually all gears are safe except for 1-11 or 2-1, if that makes sense.
Cities do lower average speed significantly, but 30k in 3 hours is indeed very slow.
Hard to diagnose from afar, but I'd say take a look at shifting technique and pedaling cadence. It's actually not so easy at first to know when to shift and which gear is right (until it becomes second nature and you never think about it again.)
Pedaling speed should be viewed as somewhat of a constant (try to aim for 60rpm at first, maybe?), and your job is to pick the gear that feels comfortable for that cadence in a given situation.
That sounds good. Will test.
