Oregon Scientific sensors
Posted: Monday 04 December 2023 19:21
Hello,
I have 3 x Oregon Scientific remote sensors and a receiver. The receiver has always received all 3 sensors pretty reliably and still does despite Domoticz problems.
I have been using an RFXCOM RFXtrx433E Transceiver for several years now, without problem.
In the last year or two, I noticed that one of the outdoor sensors was only updating once or twice per day for a bit, got gradually worse and now only updates very occasionally - last update was April 2023.Then in the last couple of weeks another sensor has started misbehaving and only updating Domoticz a couple of times a day.
Today I finally got round to doing some troubleshooting, dug out a Windows laptop and used RFXmngr to have a look. When I disabled all protocols except Oregon Scientific all 3 sensors started reporting their readings every minute as they should. I re-enabled the other protocols that I use one at a time and identified that Byron SX interferes with the Oregon Scientific sensors. When I brought all 3 sensors into the same room as the RFX433 then one of them started to work again but the other one, even sitting on a table right next to the transceiver would not report its values to RFXmngr but the Oregon Scientific receiver was still picking it up. As soon as I disabled Byron SX, all 3 sensors were immediately picked up again.
I notice in the RFX433 manual that Byron SX can interfere with Oregon Scientific but I was using both protocols together for a few years before this happened. Unfortunately I can't remember if or when I last updated the firmware on the RFXtrx433 so not sure if this could be the cause.
Now I have returned the remote sensors back to their usual places and reconnected the RFXtrx433 to Domoticz (Pi3) and the sensor which was working in the house is now not working and vice versa. All very odd...
The RFXtrx still reads other makes of temperature sensor perfectly fine and switches power sockets on and off.
Just wondering if anyone has any ideas please?
Thanks.
