Aircraft equipped with transponders transmit their altitude with reference to 1013.2 So, on a day like today where the QNH is 20 hPa above 1013.2, the difference in transmitted altitude between GPS derived altitude and "transponder" altitude is around 600 ft. So, the clever algorithms that SkyDemon uses to warn of potential collision risks aren't going to work very well... SafeSky is aware of this issue and is, I believe, trying to figure out how to fix this issue...

From their website: To determine your altitude and difference towards other traffic it will use the onboard pressure sensor. The pressure is used to calculate your pressure altitude (QNE). It is a great little unit, and cheap. Provides ADS-B in as well as traffic over internet as long as your phone have an internet connection. Works well with skydemon. https://www.airtrafficobserver.com/the-receiver/ I have no relation to the company more than as a customer, just think the unit is great and the customer support (just one person as far as I understand it) is fantastic.

The process as described by FlappingTiger worked for me too. I'll recap my steps here in case it helps anyone else wanting to get this combo going: 1. Turn on Sky Echo 2. Connect your iPad to the Sky Echo wifi 3. Start SkyDemon, Fly with Sky Echo 4. Connect your smartphone (during flight it can stay in your pocket!) to Sky Echo wifi 5. Start SafeSky (PAID version which as RidgeSkimmer points out is needed to allow traffic sharing) 6. Configure SafeSky "Navigation Software" with Enable Traffic Sharing to SkyDemon. 7. Configure SafeSky "External Traffic Device" with SkyEcho 8. Configure SafeSky "My Aircraft" with the correct ICAO unique hex code 9. "Take Off with SkyEcho" in SafeSky. 10. Now SafeSky supplements the native SkyEcho traffic with its own where possible. A few observations: 1. When I ran SafeSky on the same old-ish iPad as SkyDemon, it kinda worked but then froze shortly after take-off. 2. Running SafeSky on my smartphone fixed this problem, and the iPad SkyDemon shows its traffic just fine. 3. When running SkyDemon, I choose "Fly with SkyEcho", not "Fly with GDL 90 Compatible Device". I cannot explain exactly why this works and SkyDemon aren't too keen on engaging in technical explanations - but it works as RidgeSkimmer says, and also means the Sky Echo control menu item is retained in SkyDemon while flying (e.g. to turn ADSB-Out off and on). One possibility is that the "Take Off with SkyEcho" option in SafeSky causes it to broadcast its UDP packets on the SkyEcho's standard UDP port, and SkyDemon can't tell the difference. But that's a wild guess. 4. I suspect Android tablets and newer iPads may be better at multitasking, meaning smartphone not required. But I still like the idea of splitting the SafeSky processing load off to a different device (that's the networking/computer nerd in me I guess). Thanks to FlappingTiger for the useful post detailing all this in the first place, much appreciated.

Thanks to FlappingTiger for the useful post detailing all this in the first place, much appreciated. There is an issue if trying to do this using an Android smartphone. The phone's Android OS won't allow a mobile data connection when the WIFI link (to the SE2) is active. I haven't been able to find a working solution to this issue for Android users. I am now using the new Safesky Aero Tracker which connects via Bluetooth.

My Pixel 7 happens to work in this configuration, successfully connecting to LTE for internet and to SkyEcho WiFi at the same time.
