50% DOA

Only half of the temp probes worked. Ordered 4 and only two work. Got the run around with support. If I can get two to run then its not the wiring or the layout. Also have to ask for a wiring diagram, They need more into on there products on the same page.

DS18B20 Review

This works great. The wiring diagram and included resistor were easy to connect.

Waterproof Temperature Probe with HA

Not sure if the probe works. I cannot use this sensor with Home Assistant. If I setup this sensor via the Konnected integration the Alarm Pro constantly reboots. The only way for me get the Alarm Pro usable is to re flash the firmware but make sure you remove the Konnnected integration in HA before you re flash.

Does not work with Konnected

Sadly I have to rate this device low. You have sent me the replacement device even that does not work woth Konnected DTH. I have tried this with Arduino and it is working. So it is not that the device is at fault. Andy has been very good attempting to problem solve. In the end he sent me a replacement device but it does not work with Konnected..i.o

Temperature probe

I purchased a Waterproof Temperature Probe (DS18B20) to compare and visualize the outdoor temperature. When I opened it I saw that there was a diode but a lack of instructions for the installation was concerning. After searching Youtube for DS18B20, I was able to figure out how to hook up the unit. Other than that extra step I am enjoying the extra source of local temperature.
