Hi,
I’m facing the same problems:
My items are not updated even the thing „Netatmo API“ is ONLINE - it’s annoying. For the moment it seems sufficient to just restart the Binding via bundle:start (not the whole OH process again and again), then it’s working again for a while… but not stable. I hope, this will not be the new default when they are sailing under Legrand flag…
Cheers,
Marianne

too much cloud = stormy systems 
Your’e absolutely right! My Healthy Home Coach is the ONLY cloud basted hardware I bought – and now I know again why I hate this cloud approach so much!
Lucky us for using “just” the weather and/or security products. Imagine you have the thermostat or relays for controlling your heating via Netatmo cloud. You would have been freezing for hours by now …
That is the reason, why the thermostat of my Heaters are “cloudless”, connected local with my Fritzbox and controlled with openhab rules - also my Window sensors. 
Netatmo is less important for me, I use it in openhab only for the heater rules. all other features I use with native netatmo app
The binding doesn’t seem to request a refreshed token either.
From the last Week and till yesterday (Thursday), It is stop working again. Sinces Thursday is not refreshing any more
Crazy!

The changes are all the current values from Netatmo!
Are you on the latest snapshot?
The last error [warn] should have been fixed:
I think updating the thing is basically the same as restarting the binding. So it’s somewhat expected behavior.
Installed Version: 2.4.0.SNAPSHOT
I’ve noticed problems with this binding (or API) lately aswell (last couple of weeks perhaps), had to restart the binding many times and it keeps coming messages like deladus posted (Unable to connect Netatmo API : 500 Internal Server Error).
Using the latest testbuild M6…
I believe this is due to Netamo server. I have seen these errors as well a few times, mainly around midnight. I think it´s because Netamo is messing around.
Also the last 2-3 days, I have not been able to reach my Netamo weather station. It turned out to be due to new firmware. Had to force it to reconnect and then the message about new firmware popped up. After updating the firmware last night, it has been running fine again.
i’ve installed version 2.3.0 of netatmo binding via paper ui.
how i can install snapshot 2.4.0 and where i can download snapshot 2.4.0?
you can try M6: [OH 2.4.0 M6] Testing Results
edit: no… this PR was merged 2 days ago, so you need the latest Snap
Read in that FAQ about Snap also
I have similar problems. So far I could identify 2 reasons when no data appear in OH:
Mainly I’m faced with no. 1, thus my question is if this is the right area to investigate since no. 2 is out of influence area.
Are there alreay any issues raised to stabilize the binding?
Just to report that I am having refreshing issues too, since about 10 days on OH 2.3.0.
I have to restart the binding several times per day 
I saw that also the Netatmo App had sevaral disconnections.
To get aware of Netatmo refresh failure I implemented a notification rule, so I can do a manual restart of the binding. (I know it’s not PRO and in some way it could be done with items previous state, still it works).
If anyone is interested in annoying notifications 
…
var Netatmo_Prev_Out_Temp = null
var Netatmo_Prev_In_Temp = null
var Netatmo_Prev_Indoor_CO2 = null
var Netatmo_Watchdog_Counter = 0
rule "Netatmo watchdog"
when
Time cron "0 0/10 * 1/1 * ? *"
then
if(Netatmo_Outdoor_Temp.state.toString != Netatmo_Prev_Out_Temp || Netatmo_Indoor_Temp.state.toString != Netatmo_Prev_In_Temp || Netatmo_Indoor_CO2.state.toString != Netatmo_Prev_Indoor_CO2)
{
Netatmo_Prev_Out_Temp = Netatmo_Outdoor_Temp.state.toString
Netatmo_Prev_In_Temp = Netatmo_Indoor_Temp.state.toString
Netatmo_Prev_Indoor_CO2 = Netatmo_Indoor_CO2.state.toString
Netatmo_Watchdog_Counter=0

HI,
I’ve same Issue. I updated the github issue with this info:
https://forum.netatmo.com/viewtopic.php?f=5&t=6912
It seems Netatmo’s API have been changed
:\
That is a topic from 2016!
