Warning - Heiman HS1HT-Z+ Temp/Hum sensor
Posted: Monday 03 February 2020 9:00
Hi Folks,
I recently purchased a Heiman HS1HT-Z+ Temp/Hum sensor from China. I was intending to use this as my main living room temperature sensor for heating control. However, it looks like the device is pretty useless.
It turns out that the device is entirely unsuited for precise temperature control as it only wakes up to transmit if the temperature changes by more than 2°C or humidity by more than 5%.
The "wake up" timer is said to be every 300s by defautl, however it comes set to 86400 seconds (24 hours). If you want to change it you need to press the "net" button once (or until the led lights, it's a bit random) and then send/save the new setting in Domoticz. If you don't do this any changes seem to time out quite quickly, and certainly before 24 hours!
Finally I have had it running for 11 days and the battery (CR2450) is already down to 34%.
So it seems that it's not much good for anything.
