Further observation in relation to failsafe on the Secure actuators.
I’ve just got my hands on an SSR302. I’m using the Fibaro dual relay DTH for some testing. All is working fine and the unit does not enter failsafe after 45+ minutes contrary to what thee docs say. During my testing it stated on for in excess of 8 hours. For the record its not paired with a stat and directly connected to ST which may well have something to do with it. All good then. The unit can effectively be used as a relay to power two separate uses. Good stuff.
The SSR303 however is a slightly different beast. I’ve got 3 of these connected to a central heating zone in the house, they work well when paired with a stat (SRT321) and I have use a community developed DTH to change the set point which in turn switches the actuator (I can’t fault these, if you want a cheap stat option).
The issue arises when you pair the SSR303 actuator directly with ST. If you turn it on and leave it on for 45+ mins then it enters failsafe and turns off (as documented). My use case requires that its on for 3 hours a couple of times a day, I’ve tried pollster but the thing just won’'t stay on when switched on for more than 45-60 minutes. Shame.
I’m pretty sure that the SSR302 is a slightly different implementation to the SSR303 (there I go stating the obvious again). This is probably due to the fact the SSR302 is treated as a Z-Wave switch and the SSR303 as a thermostat.
Either way, thought I’d feedback. At the moment I’m using CoRE to turn it off/on if its been on for longer than 45 mintutes which seems to work. Not ideal.
