Thanks again. I’ll report back if I make any progress.
Progress! It works if in configuration.yaml I use my loopback dynamic dns address and forward a port instead of using my local address. I’ll take it!..although I’d like to know why.
So Jim, thank you again both for sharing your integration and for assisting.

Great Integration! Worked like champ. How do you display in UI with speed control for fan? I can get the fan to display, but have to click in to set speed. Just wondering what everyone is using
Thanks @jimpastos for your integration. For anyone who wants a more compact fan card, I modified some code by another user to work with the six speeds of the modern forms fan.

FYI, WAC Lighting, the parent company of the Modern Forms brand has started producing new fans under the “WAC Smart Fan” brand. These fans use the same API as the Modern Forms fans, except it is initially locked behind an in-app purchase.
After connecting your fan to the network and making the additional in-app purchase, @jimpastos’s custom component will work with the WAC Smart Fans.
Jim:
Thanks for the component. I am working on the interface card now. Might you share your yaml code?

I had the component working for a bit and then it spit out the error below. This may have been a coincidence but around this general time, my wife tried to turn the fan on (from the wall control) and called down the stairs that my fancy new fan was not working!

Did you manage to fix this?
You Fan’s IP probably changed (not 192.168.86.50 anymore). You should mark is as static on your router
My router assigns a fixed IP.
I was able to get things to work, but the CAUSE is the question. It looks like my wall control for the fan just goes off line from time to time. While I was working with your custom component (I was using tscibilia’s lovelace control) it seemed to fall off every day. I would pull the airgap on the wall control or toggle the circuit breaker for the fan for 30 seconds and it would reconnect immediately. Several searches of the log would show messages stating too many queries of the fan IP (sorry I did not save those!).
I will keep you informed. And thanks again.
It has been running for a whole day without having to reboot the wall control.
And thanks for the component!

Any plans to add HACS support for this integration ?

Jim:
I have your modern forms component running on 4 fans at home. All have IPs assigned by my Google mesh router. All fans have local and `Net access (WiFi and cloud access icons appear on the app). One or more fans continue to report the below error. When I ping the fan from the command line (especially when traffic has been quiescent for a while) the first response is slow (lengths up to 580ms). See below:
Reply from 192.168.86.50: bytes=32 time=586ms TTL=255

I wonder of the error comes from the component being impatient asking for the response.
Here is the error again, it appears randomly with multiple fans:

Any thoughts where I should go to further debug this?

Hmm, how is the Wifi connection to the fan? Maybe its struggling?
Another option is to limit the refresh interval. I believe the setting is per fan and defaults to 10s.
try something like
modernforms:
- host: ...
name: ...
light: ...
scan_interval: 20
Will try to increase scan interval and report back. Two of the fans are < 15 feet and line of sight from one of the Google Mesh units so signal strength should not be an issue.
Thanks!
Setting scan_interval produced this error:

I will look at the code too to see if I can correct the incompatability b/t datetime and int variable types.

Edited modernforms component, file __init__.py as follows:
Added:
import datetime
to line 3
Changed line ~66 from:
self.poll = async_track_time_interval(hass, update_action, interval)
to:
self.poll = async_track_time_interval(hass, update_action, datetime.timedelta(0,interval))
This seemed to remove the type casting error with the interval variable. Will follow up with whether the increasing the interval helped.

Thank you for this. Since there’s already a correct import at the top, what seems to have done the trick for me is just changing line 64:
self.poll = async_track_time_interval(hass, update_action, timedelta(0, interval))
Since I’m relatively new to Home Assistant, I wonder what would be the best way to confirm this change had a desired effect (i.e. actually changed the polling interval).
Context: I have two Modern Forms Roboto fans, and they have been rather wonky since I started using this integration. After about a day or so, their TCP/IP stack appears to freeze solid, and they stop responding. I have a strong suspicion it’s the “intense” polling from Home Assistant integration that is triggering a memory leak of some sort on the fans. I want to see if slower polling delays the reintroduction of the issue, or it’s simply time-based.
Thank you for the code. Please forgive me as I am really new to all this, I have my fan working with the standard cards but I really like the one you put together. Can you tell me where I need to actually put this code? I have my home assistant running on a Pi 3B. Thanks in advance for any assistance.
It is good to see I am not the only one with this problem.
And yup, did not look carefully and timedelta from datetime was already imported. Changing the singular line at ~64 was all that was needed.
I agree that a probable memory leak in the fan’s firmware seems like the most likely culprit. Slowing the polling will only eliminate this if the firmware has a garbage collection scheme. I wonder if we could command the fan to reboot in the dead of the night?
My fans have been more stable after decreasing the polling rate.
