Don't want to rely on any internet stuff.

I was just thinking that Sonoff should really do a ceiling fan controller thing next... Would be nice if it had a temp sensor integrated somehow, my current remotes measure the temp at the remote and then increase/decrease fan speed. Would love to get these just to make sure fans are turned off when left on etc, and of course they must be usable over MQTT.

Funny that I want to integrate the TH10's possibly for the bathroom extractors fans based on humidity sensor.

They are wired in with the lights now and irritate the *** out of me so figured why not make them smart to only turn on when there is enough humidity.

If you don't want internet stuffs then just Tasmota them?

Yeah I'm just saying the new ifan stuff would need to be able to run with tasmota as well.

Mine did right out of the box.

where can I get one pf these units?

so with that sonoff pow R2 I can just add a inline 20-30 amp relay to connect it to my pool pump?

How big is your pool pump? Mines .75kw and been running fine for months.

My 1.1kw pump seems fine on the pow.

Yeah... no issues with my .75kw... hell even the 1.5kw motors would be fine from my understanding since it can handle a draw of up to 3.5kw... (though I wouldn't push it that far ever)

I wonder if its possible to setup a second Pi as a roll-over incase one goes down with the home-automation stuff... real inconvenience if it happens when you're away.

Definitely possible yeah.

All you need is something that adds a floating ip between the 2 devices, which will put 1 as master and other as backup.
Then you also need something that will sync the data between the 2, so that configs/graphs ect stay in sync.

The problem however is, if the sdcard is the fault, it will be a fault on both as they both will get the same amount of writes, but there is the chance that the second one fails later or the other way around. To make it really useful tho, you need monitoring to see if something fail before both fail.

Relay would defeat the purpose of the pow, as it would only measure the power draw of the relay

ok thanks mine is also 0.75kw

That's some pool pump you got there partner! But if you're adding a relay you could just use a Basic.

 

[SmartKit]

Yeah, you're looking at 5000W+ if you're pulling 20amps or more.

I'm not convinced on the inductive loads - but you should, "in theory", be able to power about 3000W off a POW without an issue.

guys I only mentioned a 20-30amp relay as currently I have a cheap battery backup timer that powers a relay that switches the pool pump on / off

also the size of the relay's got nothing to do with what the pump draws - as long as it can cope with the initial start up spike - the pump will draw only what it designed to draw.

I just want to be sure I don't over load the sonoff and toss 380 bucks down the drain that's all.

So I wouldn't bother with a pow then.

why not?

Oh hang on
You want to go timer -> relay -> pow -> pump?

I just want to replace the current cheap setup with something better! the issue is the cheap battery backup timer tends to lose time after a few years and a few power failures.

if the pow can handle the 0.75kw pump then fine and if I can switch it on / off from my phone whenever I want - then that's cool too
