I recently bought a Homey Pro 2023 to control 3x Heatit z-trm3 floor heating thermostats, but I’m unable to connect with any of them.
I suspect a bad homey unit, but thought I should check here for advice before starting a RMA.
My first problem with the Homey occurred during setup. It refused to connect with the 5 GHz network. Homey complained about bad username/password even if I’m 100% sure it was correct. After opting for 2.4GHz the setup went fine. Homey is also updated to latest firmware.
I have followed all tips regarding Heatit connection procedure: Tested with all 3x thermostats, reset thermostats a numer of times, tried with a variety of ranges to the Homey unit from 0 cm to a few meters.
Regardless what I do Homey will not see a single unit and the Heatits shows Err after some time. (After selecting «Con» and watching the spinning circle for a while.)
Unfortunately I have no other z-wave units to test with. No zigbee units either for that matter.
Anybody got any ideas?
