Issues changing heat mode on Sinope

From the "Devices" page, I can toggle my thermostat's heat mode between "heat" and "off". This status is immediately reflected on my dashboard ("Thermostat" template). However, from my dashboard, I am unable to toggle the heat mode. The option is there, but it doesn't do anything.

Additionally, if I use the Devices page to toggle the thermostat to "off", and then use my actual thermostat to toggle it on, the new status is never reflected back on the device page. Is this expected behaviour?

Thanks for the help
