Here's another newer firmware:
http://download.controlmyhouse.net/betafirmware/wl500gP-1.0.320.trxIt fixed a couple of the issues reported. Assuming we don't find any issues with it we'll release it.
I should say its not updating correctly. (374 degrees). See the attached image!
I'm sure Vera must be reporting the temperature accurately. It's just that your house has warmed up. I suggest you call your HVAC company. <lol--that's my impersonation of the HP tech support guy helping me with my printer last month>
Actually, can you do this? Try upgrading to firmware 320. Then when it comes back, do Advanced, Logs, and check 'verbose logging'. Then click 'save'. Wait 15 seconds. Now go to Devices, click + next to the thermostat and then Z-Wave options, then 'poll now'. You should get a status window showing the state of the polling and whether it succeeded or failed. Then go to Advanced, Tech support and submit a problem report including the logs. Note that after you click 'submit' you may have to wait a few minutes before it gives you confirmation. But it is working. I've asked the web guy to provide a feedback mechanism.
Have anyone tried On/Off event?
325xi, Can you repeat the same debug steps described above to enable verbose logging, but instead of clicking 'poll now', go to Location, note vera's time and be sure it's sync'd with your watch. Now, turn on/off the light. Wait 10 minutes (it can take a while to poll depending on the type of device), and then do a tech support submission. I'll try to fix both of those issues asap.
