Nothing to do with slower networks… the mitsubishi WF RAC module is simply the worst I’ve ever worked with (and im in IT) 
It keeps connecting, disconnecting (if I look at the logs of the network) every couple of minutes, does not matter which WiFi settings you use (2.4, 5ghz, static ip or not, advanced settings etc). Here a screenshot of the network logs (and this wifi network is set to 2.4Ghz only, and close to the Airco units):
Reply van Mitsubishi over WF RAC: ”MHI QA have responded as follows:
The connection condition between the router and WF-RAC is normal as the specification of the interface (WF-RAC) doing connect / disconnect every one hour.
This is because to avoid too much cache by the communication and this operation should not affect the application.’
Everything in my house is UniFi AP 7 Pro XG with gigabit speeds and 10gb connections on LAN. When I compare this with Daikin (which I had in my previous house), that was 10x better, but yeah it is what it is I guess Thanks for the work on this plugin!
Im considering throwing out the WF RAC in the future and replace it with this: https://clima.protoart.net/shop/climacontrol-mitsubishi-heavy-industries-airtoair/?v=1a13105b7e4e as mentioned in: https://gathering.tweakers.net/forum/list_messages/2233498
The current update: 1.3.4 still times out the Airco’s in homey now. 1.3.2 was working fine.
