How many weewx-instances and skins can be run simultaneously with acceptable performance on a Raspberry Pi 3B and 4?
I wanted to put as many weewx instances as possible on one RPi3 B as I have an usv/ups board (StromPi 2) installed on it. Multiple RPi3/4 with a battery backup each would get a bit expensive. In its final form it should run at least 4 instances, maybe with the possibility to add one more sensor in the future: 2x SDR instances for 2 different outdoor sensor arrays a / b 1x interceptor driver with FOSHKplugin for sensor array a 1x USB driver for sensor array b which is recieved with the USB-console The both SDR instances will also record some sensors of the secondary sensor array each, so: sensor array a primary + sensor array b secondary sensor array b primary + sensor array a secondary (to have further redundancy if one of the instances stops or gets maintenance) I wanted to keep the standard seasons skin, aswell as install the neowx-material skin for each instance. BUT: After installation of neowx-material it already needs around 38 seconds to generate the report files for one single instance. The ftp uploads already are in 1 to 2 minutes too late for this instance, on both the seasons and neowx-material skin. Tried it with the sdr-instance, the interceptor-instance (with just the seasons skin until now) is less affected by this. Is my neowx-material config somehow broken or is this a normal beaviour for a 1 minute reporting interval with the neowx-material skin? I even wanted to add belchlertown and weather34 in the future but I guess that will be just too much, as it seems they will consume even more resources, with the live reporting possiblities? Is the performance primarily cpu or memory (sd card) dependable? -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
