Honeywell TCC login errors

@csteele and @neonturbo ... Tagging you guys in hope your experience can help me. Appreciate you in advance.

I have 2 Honeywell redlink gateways as I have 8 thermostats total - 4 on each gateway. Prior to Hubitat I used SmartThings. All devices are visible and manual changes work fine. My goal is sadly simple - I want to have two virtual switches to change the mode of the thermostats at one time. A CoolAll that will set each of the 8 thermostats to COOL. And a HeatAll that sets them all to Heat. In ST I used webcore to do this, it worked fine. Every now and then I would notice a thermostat or two wouldnt change so I would manually update.

I have the same setup in Hubitat. I setup Webcore for this ( I tried rule engine, the thermostat built in..name escaping me now..etc). I wont say this does not work, it does, it just generally fails. Reviewing logging I see the login to TCC fails, seemingly too many attempts. I have set the refresh to 30min for each tStat.

Would you have any ideas on what to do here? Just want the option to update be reliable and work.
Again, thanks. Oh, yes, I use Csteele's latest set of drivers.

Their API limit is 100 per hour now. So you are only doing 16 per hour with your 30 min polling. Are you doing any other updates to the thermos that would use their API to push you over the limit?

It just appears you may be hitting the api limit, but it may just appear that way. I replaced all my Honeywell wifi thermostats because their polling is so slow. It would take about five minutes for the thermostat to update locally when updated via the cloud. I can't imagine using 30 minute polling - I went to the T6 Zwave thermostats for instant updates and got their cloud servers out of it.

ya i wish i could use the t6 zwave.. but i have not found a zwave version like the iaq that supports eim or humidifier or duct sensors.

@user2574 Thanks..yeah I keep looking to possibly change tStats, but with 8 its pretty expensive. But it is feeling the best way.

I think that RedLink limits you to just wifi thermostats... so unfortunately you would need to find some other Zwave or Zigbee wireless thermostats and replace the whole system.
