Connection limitation? #198

Open aarner42 opened 5 years ago

aarner42 commented 5 years ago

Greetings, I've been converting a house full of Fauxmos (Belkin Wemos emulation) switches built on a LOLIN D1 MINI (esp8266) platform + Relay + LED switch. All was working well until I added the 8th or 9th device. After that point, the connection to iot.sinric.com became sporadic. I've currently got about 12 devices built - Am I getting myself blacklisted or bounced out due to excessive traffic? The devices all connect to WIFI just fine but aren't able to reach iot.sinric.com, or if they do they almost immediately disconnect. I believe I've taken care to avoid spamming the server with state updates, the debug output from the devices hasn't shown any such error anyways.

Additionally, if I switch off the circuit breakers to power down a few rooms, devices that weren't connecting will suddenly connect. Seems like there's something behind the scenes impacting because it worked great up until I got 8 or so esp8266s connected.

Please advise, am happy to share source code or anything else required. Thanks, -Aaron Dutenhoefer aarner@gmail.com

If you turn off all devices and connect only one device, does it work?

Following IPs has been blocked so far

79.13.115.184; 172.69.194.42; 188.114.102.186; 156.198.37.180;

I think the limitation coming from your router

It does work in that situation, yes. As I start switching rooms back on, invariably the last few devices powered up start having connection issues.

kakopappa commented 5 years ago

I can turn on logging on the server and we can try to diagnose what's going on now if you are up for it

aarner42 commented 5 years ago

Didn't see your earlier post about blocked IPs. As none of them are mine I'll keep investigating on my side and verify it isn't router connection enabled. Just to confirm though, once I've enabled everything, I'll have probably 50+ devices - do you see any potential scaling issues?

BTW, other than this glitch I'm loving SinRic. Very good job. I'll be sending something to help with AWS hosting fees.

aarner42 commented 5 years ago

I'm at the office right now and away from home so right now doesn't work. I first want to verify it's not router/firewall related on my end. (I've been a dev long enough to know the fault is usually mine before blaming anyone else.) If that checks out I'll get in touch to work out a time we can diagnose. I'm in CST time zone, or GMT-5.

kakopappa commented 5 years ago

50+ devices? wow that is a lot.. are going to automate the whole building?

right now it runs on a single nodejs instance and has done a pretty good job so far. With the current growth rate, I will have to add clustering support soon.

You are exactly 12 hours behind my time.. when you go back home, I will be waking up to go to work. so check and let me know.

aarner42 commented 5 years ago

Aye, it's a larger home that I'm replacing all the in-wall switches with esp8266 (d1 mini) modules. For the two-gang switches I can use a single esp8266 and drive multiple relays, but otherwise it's one esp8266-per-switch. Probably 40-ish switches, some powered shades, a couple aquarium pumps, three entrances, two garage doors...it adds up.

kakopappa commented 5 years ago

just my two cents.

Why not use a relay controller module with 8/16 relays put it in a box and mount the box to wall or a din-rail and control it using an one ESP module? Keep everything centralized so it is easy to manage downside is you have to rewire to go trough the box

aarner42 commented 5 years ago

That would have been my first choice - unfortunately it's a rented house and I can't make the sort of re-wiring changes in the walls that would be needed to support a simpler architecture like that. The way it's wired now all the lights are shared with sockets across rooms so cutting the power at the breaker would turn whole parts of the home off, not just specific lights. :-(

I believe I have figured out the issue that was affecting the connectivity. Using wireshark I was able to determine that it was the actual entire wifi session being dropped, not just the webSocket link. The cause was a 250 msec loop doing an analogRead of a current sensor (The switches are in a 3-way config and I need to check whether the light is drawing power to know the state). There's a known issue with esp8266 that analogRead() in a tight loop can cause this, and I had included a call to yield() per the docs to mitigate. Apparently that's wasn't sufficient for some of my esp8266 modules. Changing the yield() call to a delay(5) did the trick. Thanks for your input tho, it was helpful in focusing my debugging efforts.

Please let me know in the future if there's anything I can do to help out with Sinric. My primary expertise is in Java on AWS/Windows/Linux, but I've got some Node.js exposure and always eager to learn.
