Update 05/20/2022: After working with our partner, we have replicated the “No Response” error in our test environment. We have determined that the “No Response” error occurs when the Rachio 3 is switching between HomeKit hubs. The “No Response” is more likely to occur the more hubs that are present on the network. We are currently targeting our investigation into the root cause of these communication errors and will then work on scoping out the work to improve connectivity
