should be pretty easy to setup, you do also however get fans with this function already and alternatively fans with timer options etc.

I have one of those in my other bathroom, works with lights and set it to switch off after 10 minutes (setting is adjustable). But they are a bit noisy, don’t only use the bathroom to shower only and prefer some pease and quite. Thought would be better for the fan to come on only when the humidity spikes and go off when it normalizes.

yeah that's a timer one, you get ones that have both.

I am currently doing this yes.

Only difference is that I'm using a Xiaomi Aqara Temperature and Humidity sensor and a Sonoff Basic for the extractor fan.

I did find it slightly better to look for a sharp rise and fall in humidity rather than an absolute threshold humidity - argument is that during rainy days the general humidity is in any case higher and I don't want it to trigger then.

So can you set the TH10 to pick up the humidity spike?

I have this setup in my bathroom. It annoyed me that the fan would always be on when you switched the lights on, although I didn't need the fan to always be on. So I fitted a Sonoff TH16 (overkill I know, it's what I had available) with the si7021 sensor inline before the fan.

TIP: Don't use the si7021 sensor. It is very unstable above 85% humidity and basically can't measure above 85% humidity. Above 85% humidity, it would randomly error out and stop the fan and the fan would also sometimes start up with relatively low humidity but the sensor would read very high. I swapped it out for an AM2301 sensor and it works like it should.

TIP2: Try not to place the sensor to close to your shower or bath. The excessive humidy will condensate on the sensor and give inaccurate readings and the condensation will take a while to dissipate from the sensor.

With the Ewelink app the Sonoff TH10/16 can only switch on or off above or below a set temp or set humidity percentage. You have to pick either temp or humidity. It cannot switch on or off on sharp rises of temp or humidity. I am sure it can probably do that on Tasmota and HA.

Home Assistant has the perfect sensor for this. It senses the trend if the humidity is rising or declining thus allowing you to switch it on at a sharp rise in humidity.

I have what appears to be a relatively weird thing going on...

Trying to configure a Sonoff L1 LED strip, and everytime I put it into pairing mode so that eWeLink can configure it, it seems to absolutely kill my network. Anyone come across something like this before?

one thing you can try, is disabling auto on your wireless channel selection and making it a fixed channel, like channel 11. (as a side note i had to do this for my chromecast to work properly)

Yeah will get in depth with it next weekend probably.. Was just weird cos I paired a 4ch quite happily about 40 minutes before that... Also need to figure out exactly what it's doing cos it seems to boot everything off the wifi... Which is weird.

It depends on how you have your system setup but I am running pretty much what you are after at the moment.
My bathroom fans are connected to Sonoff T1's and Home assistant. I have Xioami bluetooth temp/humidity sensors in each bathroom.

Those are reading back to an ESP32 running Esphome and it is reading the output of the two bathrooms all of the time. When a certain level is reached the extractors turn on and then turn back off when humidity levels drop.

I also have an automation in Home assistant that if you turn the extractor on from the switch it will run for 10 mins and then turn itself off again. This leaves more than enough time to shower and make sure the bathroom is back to normal levels afterwards.

The placement of the humidity sensors is key though, I found having an ESPx and BME280 in the ceiling wasnt effective.
 
So I know it has been discussed partially before but I just wanted some clarification.

Is it absolutely necessary to pop off the resistors and join the inputs on an sv in order to trigger a gate motor?

Also I would like to use the gpio pins to feed off the status led output to see if the gate is closed, is this possible to view in the ewelink app?

Thank you very much for the great tips. Will try it out and give feedback.

@patrick123 and @Rocket-Boy - I haven't yet set up Home Assistant. That is going to be my next project. Currently all my automations are through ewelink.

How long do the batteries last?

You will either hate the complexity (which is very little these days) or enjoy the power (much more likely!)

Yup its definitely a lot easier now than it was when I got into it. They are getting closer and closer to version 1.0 where it will all be configured using the frontend.
 
Random question - if you have a 12v input trigger, will attaching a second device potentially damage the first device (or vice-versa)

If they are both 12 volts, then there should not be a problem, else I would suggest an opto-isolator on the second device.
