    @russss how did you end up doing #CO2 monitoring at #emfcamp? Between #fosdem and #eventinfra we are close to spending 10k€ on #airgradient because they do most things right, and we were not able to get our own hardware spun up.

    Intention is for everything to go into the eventinfra loan pool so ALL the conferences can monitor their environments.

    Before we make that step, we wanted to check if it makes sense to collaborate on fully open hardware, firmware, and software stack instead.

    @RichiH it wasn't a huge concern at EMF because we had even more ventilation than normal due to the heat.

    We had Eventinfra's Operame sensors deployed I believe, and we also have some that @gsuberland made, although we didn't get round to deploying those this year. I think he has a newer model now.

    @RichiH @russss In addition to the efforts led by @autkin , we also had a fleet of meshtastic based co2 sensors, which unfortunately are all DIY which caused issues getting approval from FOSDEM staff to use, but they worked very well as they didn't require any WiFi configuration or power supply. Over the past year meshtastic has gotten official support for many sensors such as CO2, there is however still the problem that you have to build the device yourself.
